Summary

A new chelating resin has been synthesized by modification of aminated macroporous poly(vinyl chloride) resin with pyrocatechol violet. The conditions for quantitative sorption of traces of Ti(IV), Zr(IV) and Ga(III) and quantitative elution of Ti(IV) and Zr(IV) are investigated. Accordingly, the collector can quantitatively adsorb traces of the above analytes at pH 2.0–6.0. Interferences of coexistent ions with traces of Ti(IV) and Zr(IV) can be neglected. After trace matrix separations by that collector, Ti and Zr determinations in real samples (e.g. steel, geochemical materials) can be performed with satisfactory results.
