Protocatechuic Acid Promoted Alachlor Degradation in Fe(Ⅲ)/H2O2 Fenton System

摘要：

　　In this study,we demonstrate that protocatechuic acid (PCA) can significantly promote the alachlor degradation in the Fe(Ⅲ)/H2O2 Fenton oxidation system.It was found that the addition of protocatechuic acid could increase the alachlor degradation rate by 10000 times in this Fenton oxidation system at pH =3.6.This dramatic enhancement of alachlor degradation was attributed to the complexing and reduction abilities of protocatechuic ligand,which could form stable complexes with ferric ions to prevent their precipitation and also accelerate the Fe(Ⅲ)/Fe(Ⅱ) cycle to enhance the ·OH generation.More importantly,both alachlor and PCA could be effectively mineralized in this Fenton system,suggesting the environmental benignity of PCA/Fe(Ⅲ)/H2O2 Fenton system.
