Physical and chemical conditions of sorption of a number of heavy metals the sorbent on the basis of natural mineral raw
Physical and chemical conditions of sorption of a number of heavy metals (copper, zinc) by a sorbent on the basis of natural mineral raw materials are studied. The sorbent is capable to delete various inorganic and organic compounds, such as heavy metals, sour gases from various environments (water or air), without making impacts on environment and health of the person. During research the main adsorptive and structural and physical and chemical characteristics a sorbent, such as are considered: the total volume of a time on water, moisture content, рН water suspension, porosity of a sorbent on acetone, the bulk density, an istirayemost, and also a specific surface by research of adsorption of isopropanol from water solutions of various concentration. Sorption properties of the received sorbent in relation to Cu (II), Zn (II) are studied and optimum conditions of their sorption are established. Sorption isotherms on the basis of which constants of sorption balance and the maximum values of capacity of the received sorption materials are calculated are investigated. Conditional thermodynamic parameters of sorption processes (change of an enthalpy, entropy and isobaric and isothermal potential) are determined. On the basis of the analysis of physical and chemical characteristics of the received sorbent prospects of application of a sorbent for concoction of ions of copper, zinc with extent of adsorption of metal over 90 % are shown.
