摘要：

The sorption isotherms of copper(II) ions on natural calcium heulandite at a pH of 1.7 and temperature of 298-318 K have been obtained. The exchange sorption capacity with respect to Cu(II) ions at 298 K was 0.47 mg-eqv/g. The equilibrium constants of the ion exchange and thermodynamic functions including Gibbs energy and entropy and enthalpy of sorption have been calculated. The possibility of using calcium heulandite for purification of the wastewaters of the electroplating industry from ions of heavy metals has been assessed.
