【 摘 要 】

The article develops some physico-chemical aspects presented along of copper ions adsorption in treatment of wastewaters using volcanic tuff. In the experiments volcanic tuff from Stoiana Paglisa (Romania) has been used. Different concentrations of NaCl and HCl solutions were used for activation of tuff. The increase of activation solutions'concentrations indicates an intensification of specific adsorption of copper as consequence of energetic changes of the active centers spread on the tuff surface.
