Quality Control of TriacetonamineOn March 20, 2022, Wu, Xuan; Sun, Dedong; Ma, Hongchao; Ma, Chun; Zhang, Xinxin; Hao, Jun published an article in Colloids and Surfaces, A: Physicochemical and Engineering Aspects. The article was 《Activation of peroxymonosulfate by magnetic CuFe2O4@ZIF-67 composite catalyst for the study on the degradation of methylene blue》. The article mentions the following:
In this research, a novel magnetically recoverable composite catalyst, CuFe2O4 @ZIF-67, was synthesized. CuFe2O4@ZIF-67 composite catalyst was applied to degrade methylene blue (MB) in water by activating peroxymonosulfate (PMS). The results showed that the degradation rate of MB (20 mg/L) reached 98.9% in 30 min in the 0.2-CuFe2O4@ZIF-67 (75 mg/L) + PMS (125 mg/L) system. Both ESR (EPR) studies and radical quenching experiments revealed that SO-4•, •OH, 1O2 and •O-2 were involved in the degradation of MB. We proposed a catalytic mechanism of PMS activation by CuFe2O4@ZIF-67. With the synergistic effect of Co3+/Co2+, Fe3+/Fe2+ and Cu2+/Cu+ redox cycles, it can keep its outstanding catalytic activity. Recycling tests showed that the removal rate of MB can still be maintained above 85%, indicating that CuFe2O4@ZIF-67 has good reusability. In general, owing to its reusability and excellent catalytic activity, the CuFe2O4@ZIF-67 composite catalyst has a good application prospect in water pollution control.Triacetonamine(cas: 826-36-8Quality Control of Triacetonamine) was used in this study.
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine-containing compounds are also frequently employed in synthesis as ligands or auxiliaries. Accordingly, many efforts have been devoted to the development of novel methods for the synthesis of these compounds over the years.Quality Control of Triacetonamine
