Abstract
Zero valent iron (Fe(0)) was used to reduce trichloroethylene (TCE).Some influence factors of TCE removal including Fe(0) purity, Fe(0) size, Fe(0) quality, solution pH, reaction temperature, oscillation rate and initial concentration of TCE were investigated in the batch experiments. The optimum experimental conditions were determined as: Fe(0) purity of 92%, Fe(0) size of 30 mesh, Fe(0) quality of 30mg/L, solution initial pH of 6.0 and reaction temperature of 25℃.Oscillation rate and initial concentration of TCE had little effects on TCE removal. The 5-day TCE removal rate was 90.4% under the optimum conditions.
