Stroganova E.A. RESEARCH OF THE MINERALIZATION EFFECT ON EQUILIBRIUM ADSORPTION OF GERMANIUM IONS FROM POOR SOLUTIONS USING ANION-EXCHANGE RESIN AN-31The effect of various kinds and concentrations of a mineral background of aqueous solutions on equilibrium adsorption of germanium ions using anion-exchange resin AN-31 were investigated. Working pH areas of resin using at sorption of germanium ions from chloride and sulphatic solution were established. The equilibrium adsorption data was analyzed using Langmuir isotherms. The most important equilibrium constants of germanium adsorption from solutions of various ionic forces were calculated. The factors of selectivity and charges of extracting germanium forms were found. It is offered a selectivity range of competing ions.Key words: equilibrium adsorption, anion-exchange resin, germanium, mineralization, equilibrium constants, distribution coefficient, selectivity coefficient, selectivity range.
