The Removal of Chromium(VI) by Synthesized CMC Stabilized Zero-Valent Iron Materials

Abstract:

The removal of chromium(VI) by CMC stabilized nanoscale zero-valent iron (nZVI) and the effects of reaction temperature and CMC dosage on the removal efficiency of Cr(VI) were investigated through multi-group experiments on this paper. The experiental results revealed: (1) different dosages of CMC vary the degree of impact of the removal of Cr(VI), at the concentration of 0.5 g L-1, it has the highest removal efficiency. (2)The effect of temperature on the removal efficiency is negative. The higher the temperature is, the lower will be the removal efficiency. After 120 min of treatment, the removal efficiencies of Cr(VI) at various reaction temperatures from 0, 20, 30 to 40°C were recorded as 100%, 99.75%, 97.6%, 95.75%.
