Nanocarbon-based advanced oxidation processes (AOPs) are widely used in wastewater purification However, the properties of different carbon catalysts lead to differences in the organic degradation mechanism and toxicity of wastewater treatment. Herein, this study provides insight into the differences between the oxidation of sulfamethoxazole (SMX) by carbon nanotube (CNT)/peroxymonosulfate (PMS), nanodiamond (ND)/PMS and PMS-alone systems. The pseudo-first-order reaction constant of the reaction of the SO4·–dominated CNT/PMS system with SMX is 19-fold and 30-fold higher than those of the 1O2-dominated ND/PMS system and PMS direct oxidation system at pH= 7, resp. In addition, d. functional theory (DFT) calculations and product anal. show that SO4·- mainly attacks the aniline and sulfonyl groups, while oxidation of the aniline group is the dominant mode of PMS direct oxidation and 1O2 reactivity. The formation of nitro and nitroso byproducts after SMX degradation determines the toxicity difference, and the CNT/PMS system is even more advantageous. In the experiment, the researchers used Triacetonamine(cas: 826-36-8Safety of Triacetonamine)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Safety of Triacetonamine
