Abstract

Abstract

In order to study the affecting factors in the degradation of chlorinated hydrocarbon, tetrachlrethene (PCE) was selected as target contaminant and Ni/Fe bimetal was used as reactants in batch experiments. The results show: (1) When the mass of Ni/Fe bimetal used in batch experiment was 10 g and 20 g, the reaction rates (k_obs) were 0.047 7 h^-1 and 0.09 7 h^-1, respectively. The more the Ni/Fe bimetal used in PCE degradation, the faster the reaction. (2) The reaction rates (k_obs) were 0.047 7 h^-1, 0.059 8 h^-1 and 0.088 6 h^-1 when Ni/Fe bimetal was 20-40 mesh, 40-65 mesh and 80-100 mesh, respectively. The finer the metal, the faster the reaction. (3) The reaction rates (k_obs) were 0.047 7 h^-1, 0.066 2 h^-1 and 0.073 4 h^-1 when the Ni/Fe mass ratio was 0.024%, 0.048% and 0.072%, respectively. The higher the Ni/Fe mass ratio, the faster the reaction. Further study of the optimum Ni/Fe mass ratio is needed.
