Treatment of Pb 2+-containing Mine Wastewater with layered nanometer zinc 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 85% and Pb2+ concentration in permeation liquid was lower than 0.5 mg/L,which verified that Nanomaterials is effective for the removal of heavy metal ions, and the concentration liquid can be reclaimed.
