The isotherm of the adsorption of Ni2+ ions on complex sorbents (activated bentonite to shungite is 1:1) according to the Langmuir and Freundlich’s models was drawn; the type of adsorption isotherms according to the S. Brunauer’s classification was established. The values of the maximum sorption capacity of Гmax sorbents relative to Ni2+ ions were calculated. Based on the calculated coefficients of the Langmuir and Freundlich's equations, the specificity of the process of sorption of Nickel ions with the formation of a monomolecular layer was determined. The dependences of the degree of absorption of Ni2+ ions by complex sorbents on the duration of the sorption process were obtained. The ratio of solid state of matter (comprehensive sorbent) to liquid was experimentally determined.83-87enenvironmental securitynatural sorbentssorption isothermwastewater adsorptionArticle© Національний університет “Львівська політехніка”, 2029© Petrushka I., Petrushka K., Bliatnyk B., 20205doi.org/10.23939/ep2020.02.083Petrushka I.
