%X Core-shell Fe-FeOxH2x-3 was prepared of by NaBH4 reductive methods. The catalyst showed higher activity for the removal of humic acid than Nano-zero-valent Iron in the presence of H2O2 under near-ultraviolet (365 nm) light irradiation. The results indicated that iron oxides on the Zero-valent iron surface accelerated interface electrons transfer to enhance the reaction efficiency. The effects of the dosage of H2O2 , initial concentration of humic acid, and initial pH were investigated. The results indicated that the optimal H2O2 dosage was 5mmol·L-1. The catalyst exhibited good catalytic activity when initial solution pH varied from 5 to 9. Humic acid was discoloration and the remove of TOC reached about 60%.The trihalomethane formation potential (THMFP) was declined after the humic acid was treated.
