Treatment of Chromium-Containing Mine Wastewater with Layered Nanometer Co3O4 Hydroxide
Experiment was made to study heavy metal ion mining wastewater.The effect of Temperature, pH, Initial concentration, coexisting ions and time on the performance of Nanomaterials were investigated. Results showed that removal efficiency of heavy metal ions was higher than 86% after adsorption treatment of containing Cr(VI) mine wastewater, Cr(VI) concentration in permeation liquid was lower than 0.1 mg/L, and the concentration of Cr(VI) ions reaches the first class of irrigation water quality standards , which verified that Nanomaterials is effective for the removal of heavy metal ions, and the concentration liquid can be reclaimed.
