The results of adsorption properties of complex
natural sorbents in relation to the neutralization of zinc ions
from wastewater are presented. The adsorption isotherm of
Zn2+ ions on complex sorbents (clinoptilolite-shungite) (1:1)
according to Langmuir and Freundlich models is constructed,
the type of adsorption isotherms according to S. Brunauer
classification is established. The value of the maximum
sorption capacity of Gmax complex sorbents for Zn2+ ions is
calculated. The peculiarities of the sorption process of zinc
ions with the formation of a monomolecular layer based on the
calculated coefficients of the Langmuir and Freundlich were
found. The optimal conditions for the dependence of the
degree of absorption of Zn2+ ions by complex sorbents on
the duration of the sorption process are determined. The
ratio “solid (complex sorbent) – liquid” was determined
experimentally.
