The adsorption of Cu2+ by chernozems and parent rocks in Rostov region has been studied under laboratory conditions. It is shown that the adsorption isotherms are described by the Langmuir equation. The Langmuir equation parameters (KL and C∞) have been calculated for all of the studied samples. It is shown that the values of C∞ are in close negative correlation with the values of cation exchange...
