Abstract:
Nanoscale Pd /Fe bimetallic particles were prepared by a modified liquid reduction method and were applied to degradate 2,4 -dichlorophenol. Some factors,such as Pd /Fe ratio and initial pH,were studied in the course of 2,4 -dichlorophenol degradation. The results showed that particles with small size were dispersed more evenly and the average diameter was 50 nm. The degradation of 2,4 -dichlorophenol followed the pseudo-first-order reaction kinetics. The results of quantum-chemistry computation and the experiments indicated that the chemical environment of the chlorine atoms had significant influence in the process of degradating 2,4 -dichlorophenol.
