Tan, Chaoqun;Wu, Haotian;He, Huan;Lu, Xu;Gao, Haiying;Deng, Jing;Chu, Wenhai research published 《 Anti-inflammatory drugs degradation during LED-UV₃₆₅ photolysis of free chlorine: roles of reactive oxidative species and formation of disinfection by-products》, the research content is summarized as follows. Light-emitting diode (LED) is environmentally friendly with longer life compared with traditionally mercury lamps. This study investigated the non-steroidal anti-inflammatory drugs (NSAIDs)- phenacetin (PNT) and acetaminophen (ACT)- removal during LED-UV (365 nm) photolysis of free available chlorine (FAC). Degradation of PNT and ACT during LED-UV₃₆₅/FAC treatment at pH 5.5-8.5 followed the pseudo-first order kinetics. The presence of hydroxyl radicals (·OH), reactive chlorine species (RCS), and ozone (O₃, transformed from O (3P)) were screened by using scavengers of ethanol (EtOH), tert-Butanol (TBA), and 3-buten-2ol, and 4-hydroxy-2,2,6,6-tetramethylpiperidine (TEMP), and quantified by competition kinetics with probing compounds of nitrobenzene (NB), benzoate acid (BA), 1,4-dimethoxybenzene (DMOB). Higher pH would lead to decrease of ·OH contribution and an increase of FAC contribution to PNT and ACT degradation It has been determined that the contribution of O₃ to degradation of PNT and ACT was less than 5% for all pHs, and O₃(P) reacts toward EtOH with second-order constant of 1.52 x 109 M-1s-1. LED-UV₃₆₅/FAC system reduced the formation of five typical CX3-R type disinfection byproducts (DBPs) as well as the cytotoxicity and genotoxicity of water samples at pH 5.5 and 8.5, compared with FAC alone. The decrease of DBPs formation resulted from fast FAC decomposition upon LED-UV₃₆₅ irradiation A feasible reaction pathway of DBPs formation in the LED-UV₃₆₅/FAC system was examined with d. functional theory (DFT). For FAC decay during LED-UV₃₆₅/FAC with effluent from wastewater, the residual FAC in 15 min was 0.8 mg/L (lower than limit of 0.2 mg/L) once initial FAC was 2.0 mg/L. The results indicate that more tests on the balance of target pollutant removal efficiency, residual FAC and cost should be explored in LED-UV₃₆₅/FAC system for application.

Waste resource recovery and water pollution control are two important issues in environmental protection. In this study, ZnFe₂O₄ prepared from spent alk. Zn-Mn battery was combined with g-C₃N₄ (CN) to form ZnFe₂O₄/g-C₃N₄ (ZFO-CN) step-scheme (S-scheme) heterojunction photocatalyst to eliminate bisphenol A (BPA) in the presence of peroxymonosulfate (PMS) under visible light (Vis, λ ≥ 400 nm). Results revealed that the ZFO-CN possessed an outstanding photocatalytic performance, which was attributed to the superior visible light harvest capacity and unique S-scheme charge transfer pathway as evidenced by XPS and electrochem. test. Reactive species including SO^•-₄, ^•OH, ^•O^–₂, ¹O₂ and h⁺ co-existed in the system, among which the non-radicals including ¹O₂ and h⁺ were inferred to be the predominant oxidation species based on the result of chem. quenching experiments The effects of catalyst dosage, PMS concentration, initial pH and inorganic ion (HCO^–3, Cl^–, H₂PO^–₄, NO^–₃ or NH⁺₄) on BPA removal were investigated. At 0.3 g L^-1 ZFO-CN-0.5, 0.5 mM PMS and 60 min reaction time, more than 97.7% BPA was decomposed under visible light irradiation over a wide pH range of 3.5-9.0. This work provides a promising approach of constructing spent battery-derived spinel oxides into a high-efficiency heterojunction photocatalyst to activate PMS for practical wastewater treatment.

Tian, Shi-Qi;Wang, Lu;Liu, Yu-Lei;Ma, Jun research published 《 Degradation of organic pollutants by ferrate/biochar: Enhanced formation of strong intermediate oxidative iron species》, the research content is summarized as follows. Biochar draws increasing attention as soil amendment, carbon sink, slow-release fertilizer, and adsorbent. Herein, it was interesting to find out that among 11 kinds of com. biochar, 3 of them facilitated ferrate oxidation of sulfamethoxazole (SMX). With the addition of biochar, oxidation rates of 5 kinds of organic pollutants (including antibiotics, pharmaceuticals, and personal care product) increased by 3-14 times, and the total organic carbon (TOC) removal ratio increased by 2.4-8 times. Radical scavenging experiment, ESR (ESR) anal., and probe compound (sulfoxide) oxidation experiment showed that no radical but intermediate iron species [Fe(IV) and Fe(V)] participated in the oxidation reactions. Redox-active moieties (phenolic hydroxyl) on biochar interact with ferrate as electron shuttle and enhance the formation of intermediate iron species through electron transfer. The intermediate iron species not only interacted with organic pollutants and accelerated their transformation, but also corrupted (oxidized) the phys. structure of biochar and expanded its surface area and pore volume Increase of surface area and pore volume of the spent biochar in turn resulted in the improved adsorption capacity. In addition to eliminating emerging organic pollutants, ferrate/biochar removed 8.7%-31.6% of TOC in authentic water and decreased the formation potential of 20 kinds of chlorinated disinfection byproducts (DBPs) by 9.2%-23.9%.

van Iperen, Jolanda;van Keulen, Henk;Keune, Katrien;Abdulah, Kanaan;van Langh, Robert research published 《 Crystalline Deposits in New Display Cases at the Rijksmuseum: Characterisation and Origin》, the research content is summarized as follows. An unusual phenomenon occurred in new display cases at the Rijksmuseum four months after their installation in Apr. 2013. White deposits were visible on glass windows, silicone door gaskets, black structural adhesive seals, and on works of art. The works of art most affected by these deposits were bronze sculptures, wooden and waxed objects, tempera, and oil paintings. It was found that TMP-ol, which is part of the UV-light stabilizer Tinuvin-770, emitted from the structural adhesive Terostat-9220. Terostat-9220 was used in large quantities in the display cases to adhere glass windows to metal parts. The carboxylic acids derived from both construction materials used to build the cases and from conservation materials present on the exhibited works of art. The carboxylic acids involved were 2,4-dichlorobenzoic acid, formic acid, methacrylic acid, palmitic acid, and an unknown carboxylic acid, resp. emitted from peroxide-cured silicone gaskets, panels of medium-d. fiberboard (MDF), UV-adhesive, beeswax containing products, and from an unknown acidic conservation product or binding medium. The identification of the crystalline deposits was supported by their syntheses in the laboratory Since 2013, similar deposits have been observed in a number of museum collections worldwide. A treatment for preventing further growth of the deposits was developed and applied in the Rijksmuseum showcases.

Wang, Da;Xu, Haodan;Ma, Jun;Lu, Xiaohui;Qi, Jingyao;Song, Shuang research published 《 Morphology Control Studies of MnTiO₃ Nanostructures with Exposed {0001} Facets as a High-Performance Catalyst for Water Purification》, the research content is summarized as follows. Novel single-crystal hexagonal MnTiO₃ nanosheets with exposed {0001} facets have been synthesized via a simple one-pot hydrothermal method using NaOH as a mineralizer and tetraethylammonium hydroxide (TEAH) as a morphol. controller. The intermediate morphologies of MnTiO₃ nanostructures such as nanoparticles, nanowires, nanorods, and nanodiscs are trapped kinetically by adjusting the synthesis conditions. This approach enables us to elucidate the growth mechanisms of MnTiO₃ nanosheets based on the tetraethylammonium cation adsorption abilities on different MnTiO₃ crystal facets combined with d. functional theory calculations Dissolution and recrystallization processes are involved during the MnTiO₃ crystallization The surface-controlled MnTiO₃ has been found to be effective as a catalyst for ozonation in the degradation of 4-chlorophenol (4-CP). Within typical exptl. conditions (catalyst dosage = 0.3 g L^-1, [4-CP]₀ = 50 mg L^-1, [O₃] = 20 mg L^-1, gas flow = 0.1 L min^-1, pH 6.8, and T = 293 K), the total organic carbon (TOC) removal efficiency of 4-CP in catalytic ozonation with well-structured MnTiO₃ (MnTiO₃-180-10 sample) was 76.3% after 60 min, compared with only 22.1 and 38.5% TOC removal in the absence of catalyst and with uncontrolled MnTiO₃ (MnTiO₃-no TEAH sample), resp. Benefiting from the high exposure percentage of {0001} facet, mixed-valences of manganese, surface hydroxyl groups, and the enrichment Lewis acid sites provided by Mn and Ti, the morphol.-controlled MnTiO₃ nanosheets can be applied as heterogeneous catalytic ozonation catalysts which exhibit excellent pollutant degradation We anticipate that MnTiO₃ can be a promising candidate material for the application in remediation of organic pollutants in water.

Shi, Jinyu;Sun, Dezhi;Dang, Yan;Qu, Dan research published 《 Characterizing the degradation of refractory organics from incineration leachate membrane concentrate by VUV/O₃》, the research content is summarized as follows. In this study, we used a combined vacuum-UV (VUV) and O₃ process treating the chem. precipitation pre-treated incineration leachate membrane concentrate to further decompose substantial refractory organics which led to membrane organic fouling in the subsequent membrane distillation process. The highest removal of COD (88.1%) was achieved when 50 mg/min of O₃ dosage was used at a pH of 11.5-12. Multi-spectrum methods, mol. weight distribution (MW), gas chromatog.-mass spectrometry (GC-MS), two-dimensional correlation spectroscopy (2D-COS), and hetero-spectral 2D-COS were used to investigate the organics degradation mechanism. The combined action of O₃ and hydroxyl radicals (·OH) effectively degraded macromol. organics with high aromaticity and high conjugation (mainly distributed at 1-3 kDa) into aliphatic products with lower mol. weight (<1 kDa) and simple structures. The order of organics that were oxidized were humic-like acids > fulvic-like acids > protein-like substances. Organic acids (acetate, propionate, and butyrate) also accumulated in the VUV/O₃ systems.

Sun, Hongwei;He, Fei;Choi, Wonyong research published 《 Production of Reactive Oxygen Species by the Reaction of Periodate and Hydroxylamine for Rapid Removal of Organic Pollutants and Waterborne Bacteria》, the research content is summarized as follows. Periodate (PI, IO₄^–) can be activated by hydroxylamine (HA), resulting in rapid removal of organic pollutants (within seconds). While previous studies on PI-based advanced oxidation processes proposed iodate radical (^•IO₃) as the major reactive species, no evidence of ^•IO₃ production was observed in the present PI/HA system. Reactive oxygen species (ROS) including ^•OH, HO₂^•, and ¹O₂, are proposed to be the main oxidants of the PI/HA system, as supported by tests using scavengers, chem. probes, and spin-trapping ESR. To minimize the risk of toxic iodinated byproduct formation caused by reactive iodine species, e.g., HOI and I₂, the HA:PI molar ratio was optimized at 0.6 to achieve a stoichiometric conversion of IO₄^– to iodate (IO₃^–), a preferred non-toxic I species sink. The PI/HA system also efficiently inactivated Gram-pos. and Gram-neg. bacteria, producing ¹O₂ as the dominant disinfectant. The ROS production mechanism was also assessed and is discussed in detail. This work offers a simple, highly efficient option for PI activation and ROS production which may find useful applications where urgent, rapid toxic pollutant removal is needed.

Photocatalytic technol. assisted via peroxymonosulfate (PMS) has good potential in water treatment. In this study, the Co₃O₄/Bi₂WO₆ composite was constructed via an in-situ calcination process and used to activate PMS for the degradation of ciprofloxacin (CIP) under visible light irradiation The obtained 5 wt% Co₃O₄/Bi₂WO₆(CBWO-2) can highly effectively remove 86.2% CIP within 5 min visible light irradiation in presence of PMS. The excellent degradation performance of Co₃O₄/Bi₂WO₆/PMS system can be attributed to the synergistic effect between p-n heterojunction and PMS activation. The conduction band and valence band deviation between Co₃O₄ and Bi₂WO₆ were calculated by XPS techniques. Besides, DFT calculations were performed to further confirm the internal structure between Co₃O₄ and Bi₂WO₆. This work not only provides an approach to fabricate heterostructures but also indicated that Co₃O₄/Bi₂WO₆/PMS/Vis system is a potential environment remediation alternative for the efficient removal of recalcitrant organic compounds from wastewaters.
