Abstract
The article presents the results of original investigations of the thermodynamic laws of sorption extraction of Ni2+, Zn2+, Cu2+from wastewater. As an adsorbent, a natural zeolite from the Holinsky deposit of the klinoptilolite type, modified with a sulphur polymer, obtained from waste in the production of epichlorohydrin was proposed. The limiting parameters of the adsorption process are described by the Langmuir equation. The graphical method the limiting value of adsorption, the adsorption equilibrium constant, the differential heat of adsorption, the adsorption rate constant, the activation energy, the Gibbs energy was founded. It is proved that the investigated processes obey the laws of physical adsorption and are spontaneous.
