Title: | Quantitative determination of major cadmium and zinc content of basic zinc@ alloys comprises separating cadmium and zinc by selective elution on ion exchange resin, breaking up sample, adjusting acidity, retaining cadmium and zinc, etc. | Other Titles: | Procedeu de dozare cantitativa a continuturilor majore de cadmiu si zinc din aliaje pe baza de zinc | Authors: | Debiasi, Rodica | Keywords: | Cadmium;Zinc;Quantitative determination | Issue Date: | 30-Jun-1997 | Abstract: | Cadmium and zinc are quantitatively separated by selective elution on ion exchange resin, and the sample is broken up in hot solution containing 1 :1 hydrochloric acid (HCl), to complete dissolution. The acidity is adjusted with HCl (3.5 M) and cadmium and zinc are retained on a quaternary ammonium salt-type anionite. Selective elution of zinc and cadmium is carried out, with various molarity HCl solutions and each metal is titrated at controlled pH with sodium-EDTA in the presence of black eriochromium T. |
