摘要：

In this work, the wastewater containing sulfate ions, nitrate ions or chloride ions was used to investigate the performance of anions in copper removal by mechanically activated calcium carbonate. The copper removal from wastewater containing sulfate anion achieved almost 99% with the CaCO3/Cu molar ratio of 1:1. However, the copper removal from wastewater containing nitrate and chloride anions are lower than 20% and 35%, respectively. The precipitations from wastewater containing different anions were analyzed by using XRD, FTIR, SEM-EDS and XPS, respectively. Cu (II) in wastewater containing...
