Abstract

An investigation on the effects of humic acid (representing NOM) on TCE (a typical organic contaminant) removal by Fe0 in batch settings was carried out. Inhibitory effects of humic acid on Fe0 towards TCE removal were observed. At early stage of the experiments, humic acid might partition with TCE, and the adsorption or deposition of humic acid onto Fe0 surface would further facilitated TCE immobilization. Once the reduction reactive sites on Fe0 surfaces were covered by accumulated humic acid and the partition of TCE to humic acid became saturated, TCE removal in Fe0 was observed retarded.
