Retrieved new modified sorbent (SV-1-A) on the basis of molds Astrakhan region, representing a unique absorber. This absorber can remove acid gases, heavy metals, various organic and inorganic compounds from the air and water, without causing harm to human health. The introduction in the composition of the mixture components of pyrolusite will oxidize as low molecular weight organic and inorganic compounds. and the presence of sodium chloride solution allows you to get a micro-porous structure. The main physico-chemical and adsorption-structural characteristics the obtained sorbent: porosity sorbent on from acetone, total volume of the pore water, moisture content, pH water suspension, bulk density, abrasion, as well as the specific surface through to study the adsorption of isopropanol from the solutions of different concentrations. The modified sorbent (SV-1-A) on the basis of a molding of the Astrakhan region is received and investigated. Adsorption of ions of metals (copper, zinc and cadmium) on SV-1-A sorbent is studied. Comparative studying of sorption of metals on a considered sorbent is carried out. Isotherms of static sorption of ions of metals from water solutions are studied, change of an enthalpy (∆H), isobaric and isothermal potential (∆G) and entropy (∆S) of sorption are calculated. Calculated kinetics of sorption of ions of copper, zinc and cadmium in water solutions. The results may be used for purification of water from ions of copper, zinc and cadmium.
