Abstract

[Objective] The aim was to study the removal of carbon tetrachloride (CT) by Cu/Fe bimetal. [Method] The feasibility and influencing factors (Cu ratio, dosage and pH) of the removal of CT by Cu/Fe bimetal were studied by batch experiment, and the long-term performance of Cu/Fe bimetal was studied by column test. [Result] Cu/Fe bimetal had a good performance in CT removal, with an overall CT removal rate of 97.90%. Cu/Fe bimetal with higher Cu ratio and bigger dosage brought better removals of CT. Slight acid condition was beneficial to the removal of CT by Cu/Fe bimetal. Cu/Fe bimetal had a better long-term performance in CT removal than zero-valent iron, because its lifetime was two times more than that of zero-valent iron. [Conclusion] The research provides theoretical basis for studies on the dechlorination performance of bimetal.
