Zirkonium sorption by chelating polymer sorbents with o,o'-dioxyazo analytical functional group

Complexing properties of synthesized polymer chelating sorbents (PCS) with o,o'-dioxyazo-functional analytical group and zirconium sorption are investigated. Quantitative correlations of pK'OH values of functional groups of sorbents (FGS) with the stability of zirconium chelates (lgβ) were established for the study into the effect of peculiarities of structural and acid-base properties of FGS on parameters of chemisorption of Zr ions. Received correlations realise quantitative prediction of physicochemical parameters of sorbents, their chelates and directed synthesis, application of PCS for zirconium concentration in analyses of native and industrial objects
