Abstract:
A residue containing 18.80 wt. % Cr and 3.11 wt. % V was obtained from a wastewater treatment plant. Experiments on vanadium and chromium leaching from the residue were carried out by sulfuric acid, sodium hydroxide. The best leaching performance was showed by the acidic leaching, in which process, the residue was leached with sulfuric acid at 90 ｛C for 120 min with the liquid每solid ratio of 4:1 ml.g-1. The leaching efficiency of vanadium and chromium could reach a maximum value of 90.32% and 99.31%, respectively. While in alkaline leaching process, the high selectivity for vanadium was observed. The leaching efficiency increased from 62.64% to 91.71% enhanced by an electric field. Hydrogen peroxide was also introduced to enhance the leaching process of vanadium and chromium, the leaching efficiency of vanadium and chromium could reach up to 86.49% and 98.60%, respectively.
