Abstract

Isotherms of sorption of 2- GeO 3 and 2- Zn(OH) 4 on a synthetic sorbent are received. The thermodynamic description of sorptionisotherms analogue of the Lengmjur equation is offered. Values limiting and seeming constants of sorption equilibrium, apparent constants and Gibbs energy of reaction. Selectivity of sorption on anionite in relation to germanium is shown.
