FEATURES OF SYNTHESIS OF THE MIXED HYDROXIDE SORBENTS AND THEIR SORPTION PROPERTIES CONCERNING CATIONS OF NON-FERROUS METALS

Sorption properties of synthesized multicomponent (Mg, Al, Zn and Mo-containing) hydroxide sorbents were investigated. Isotherms of static sorption of cations of non-ferrous metals from model solutions were studied. In the range of the studied concentrations of metals in solutions, sorption is well described by Langmuir eguation linearization of which allowed determining the optimum capacity (Amax), eguilibreum constant (Kegriab.) and Gibbs's (G) energy of complex sorption process. Data of sorption tests of sorbents from and salt composition of the washing waters obtained by sulphatie processing of Dashkesan cobalt ore were presented.
