Physicochemical regularities of boron sorption by anionites with different structure of functional groups

A study was made on physicochemical regularities of boron sorption by anionites with groups of N-methylglucamine (1) and tris(oxymethyl)-aminomethane (2) in the form of free amine and Cl-form at different concentrations of sodium chloride in the solution. It is shown that disolvate complex forms during sorption. Equations, describing adequately the experimental curves were obtained, and parameters, characterizing the process of boron sorption by mentioned anionites, were calculated. Higher efficiency of groups 1 in ionite structure, as compared to groups 2, during formation of disolvate complexes of nitrogenhydroxyl-containing groups with boron anion, was established
