Abstract
The sorption properties of natural and
complex sorbents for neutralization of Ni2+ ions from the
water environment were studied. 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.
