The article was written by Shen, Minxian; Huang, Zhujian; Luo, Xuewen; Ma, Yujia; Chen, Chengyu; Chen, Xian; Cui, Lihua. The article contains the following contents:
Fenton reaction is widely used as a unique oxidation method for industrial wastewater treatment; however, it generates a massive amount of Fe sludge, which mostly contains other hazardous heavy metal wastes which can harm the environment and humans. This work proposed a sustainable method to eliminate side effects of the Fenton reaction and to transform Cu-containing Fenton sludge into an efficient catalyst for peroxymonosulfate (PMS) activation for tetracycline (TC) degradation The existence of Cu, which can increase sludge O2 vacancies, was attributed to the activation efficiency compared to Fe sludge with no Cu. X-ray diffraction and XPS results showed Fe is present as α-Fe2O3 and γ-Fe2O3; Cu mostly exists as Cu2+. Catalyst and PMS doses, pH, and recycling time effect on PMS reaction was illustrated. OH-, SO4- O2-, and 1O2 were the critical reactive oxygen species. TC decomposes into CO2 and water through six possible pathway processes with these free radicals. Given its sustainable treatment and high catalytic efficiency, dealing with Fe sludge which contains heavy metals serves as a modal practice for harmful wastewater treatment and can be popularized for broader applications. The experimental process involved the reaction of Triacetonamine(cas: 826-36-8Related Products of 826-36-8)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is ubiquitous structural motif widely occurred in diverse synthetically and naturally occurring bioactive molecules. Piperidines are an immensely important class of compounds medicinally: the piperidine ring is the most common heterocyclic subunit among FDA approved drugs.Related Products of 826-36-8
