Влияние бренстедовской кислотности на межфазное распределение Co2+ и Cu2+ в системах почва-раствор

Abstract

The concentration dependence of the sorbtion of cobalt(ll) and copper(ll) by the sod-podzol soils by the methods of potentiometry and microscale phrontal chromatography has been investigated. The pH-interval and the depth of the soil horizon were varied from 4 to 11 and from 0 to 160 sm accordingly. The combination of potentiometry and microscale phrontal chromatography methods provides the quantitative estimation of the integral degree of immobilization of heavy metals by soils as well as the contribution of exchange and overequivalent sorbtion.
