• Electronic scrap

A solid-phase extraction method for zirconium(IV) enrichment in nitric acid media using a column packed with Amberlite XAD-2 impregnated with Cyanex272 is proposed. The optimum conditions for quantitative sorption and desorption of zirconium(IV) were investigated. The method developed was applied for the isolation of zirconium(IV) from complex synthetic mixtures and an electronic scrap sample. A USGS standard soil sample (GXR-2) was validated for the separation and recovery of zirconium(IV). The limit of detection for zirconium(IV) was 3.2gdm(-3) and reusability for more than 27 cycles was observed with a relative standard deviation of 0.8%.
