Fe, N-doped carbonaceous catalyst activating periodate for micropollutant removal: Significant role of electron transfer

In this study, the performance of periodate (PI) on sulfadiazine (SDZ) degradation was evaluated using coagulation solid waste fabricated catalyst (CWBC), obtained by simple pyrolysis. SDZ effectively underwent 98.94% remove within 90 min in the CWBC/PI system. Electron transfer was the predominant mechanism due to the development of an electronic cycle among SDZ, CWBC and PI, where the O2•−, PFRs, and the reactive iodine species had minor...
