The sorption of molybdenum by polymeric chelate-forming sorbents with the o-hydroxy〈1-Azo-1′〉o′-hydroxy functional group

The sorption of molybdenum by synthesized polymeric chelate-forming sorbents (PCSs) based on hydroxypolystyrene and a structural fragment with o-〈1-azo-1′〉o′-hydroxybenzene was studied. A mechanism of the sorption of molybdenum(VI) was suggested and substantiated. Qualitative correlations between the most important physicochemical parameters of the sorbent, sorption process, and sorbate (chelate) were established and described. The correlations can be used to quantitatively predict the physicochemical parameters of sorbents and their chelates for the purposes of synthesis, the use of PCSs for the concentration and isolation of elements, and physicochemical studies.
