A new chelating ion exchange resin based sensor for zinc ions

Abstract
A chelating ion exchange resin membrane incorporating salicylaldoxime–formaldehyde exhibits excellent selectivity for zinc ions with a concentration range from 3.0 × 10–6 to 1.0 × 10–1 mol dm–3(0.20–6500 ppm). The sensor can also be used in partially non-aqueous systems having 40% non-aqueous content.
