A chelating sorbent was obtained by deposition of 1-(2-pyridylazo)-2-naphthol on Amberlite XAD-4. The analytical characteristics of the sorbent were established and optimum sorption conditions for Cu, Zn, Fe, Cd, Ni, and Pb under static and dynamic conditions were determined. The sorbent was applied to analysis of river water. After group separation of traces of metals on the sorbent and subsequent elution with hydrochloric add, the metals were determined in the effluent by atomic-absorption spectrophotometry.
通过将1-(2-吡啶偶氮)-2-萘酚沉积在Amberlite XAD-4上获得了一种螯合吸附剂。确定了该吸附剂的分析特性，并测定了铜、锌、铁、镉、镍和铅在静态和动态条件下的最佳吸附条件。该吸附剂用于河水分析。在吸附剂上对痕量金属进行分组分离，随后用盐酸洗脱后，通过原子吸收分光光度法测定流出物中的金属。
