Abstract
A chelating sorbent based on a copolymer of maleic anhydride with styrene containing fragments of p-aminobenzoic acid is synthesized. The sorption and complexing properties of the modified sorbent relative to thorium (IV) are studied and the main quantitative characteristics of metal ion sorption are determined. An isotherm of thorium sorption with the synthesized sorbent is constructed and optimal concentration conditions (pH = 4; V = 20 ml; msorb = 0.05 g) are specified. Calculate value of the sorption capacity is 853 mg/g (CTh = 8 Ч 10–3 mol/liter). The effect of various mineral acids (HClO4, H2SO4, HNO3, HCl) on desorption of thorium (IV) in static and dynamic conditions is studied. The maximum desorption of thorium (IV) occurs in nitric acid. The degree of extraction of thorium (IV) ions under optimal conditions exceeds 92%. A technique of sorption-photometric determination of thorium (IV) in seawater is developed.
