Abstract
The article describes the results of environmental sustainability and absorption capacity of the most common soil of the Republic of Kazakhstan. The types of soils, the most resistant to contamination with lead. It was found that the absorption of lead studied soils process occurs as a result of joint actions such as cation exchange mechanism and the mechanism of surface complexation. The dynamics of the process of absorption, calculated the rate of absorption of lead soil. Determined that the absorption of single-element soil accumulate more lead than the Polyelement and single-element contamination is less of an environmental threat. The dependence of the processes of absorption of lead from the physical and chemical properties of soils and the correlation coefficients were calculated. On the basis of the detected absorption processes depending on the concentration of lead source solutions for Langmuir equations calculated figures lead the thermodynamic state in the soil - the value of the maximum absorption and bond strength. Calculated potential buffer capacity of soils.
