Abstract

Abstract: A kind of composite catalyst TTFA@Co2+@ZrDP was prepared by coordination among Co2+, ZrDP (a kind of Zirconium phosphonate with 1,4,7,10-tetraazaheterocyclic ring in skeleton) as carrier and TTFA (2-thiophene formyl trifluoroacetone) as chelating ligand. The catalytic activity of the composite was studied in oxidation degradation reaction of safranin T under the existence of peroxymonosulfate as oxidant. The results indicate that the catalytic activity of TTFA@Co2+@ZrDP is closely related to its particle size, the content and dispersion of Co2+ supported, and TTFA was found to promote the transfer of electrons during catalytic reaction and enhance the catalytic ability of the Co2+. 100.00% of Safranin T could be degradated by TTFA@Co2+@ZrDP in some certain conditions under the existence of peroxymonosulfate and the catalyst has good reusability.

Key words: Zirconium phosphonate, Safranin T, Peroxymonosulfate, Degradation
