Beryllium(II) sorption from aqueous solutions by polystyrene-based chelating polymer sorbents

Abstract

Optimal parameters of beryllium(II) sorption from aqueous solutions by polystyrene-based sorbents have been studied, namely: optimal sorption acidity (pHopt), pH providing 50% sorption (pH50), optimal time (τ, min) and temperature of quantitative sorption. The sorption capacities of the sorbents under study (SCSs) for beryllium(II) have also been determined; sorption isotherms have been constructed. The parameters determined for beryllium(II) sorption by chelating polymer sorbents (CPSs) make it possible to select the most efficient sorbent for practical use.
