Abstract
A morin chelating resin was synthesized using aminated poly(vinyl chloride) as the starting material, and the optimum conditions for the synthesis were established. The parameters governing the characteristics of the resin for the adsorption of MoVI and WVI including acidity, flow rate, rate constant, saturated capacity of adsorption, effect of re-use, interfering ions and desorption were investigated. The MoVI and WVI concentrations in standard samples were determined by using inductively coupled plasma optical emission spectrometry, with satisfactory results. For concentrations of MoVI and WVI of 0.4 mg l–1, the relative standard deviation was 2.8% for MoVI and 2.6% for WVI. The structure of the chelating resin was deduced by infrared spectrometry, and the mechanism of the enrichment of MoVI and WVI is discussed.Keywords
