| Abstract: | A method for the determination of arsenic,antimony,bismuth, selenium,tellurium in higher purity copper cathode is described.Arsenic,antimony,bismuth,selenium, tellurium is separated from copper matrix by lanthanum hydroxide coprecipitation and determined by HG AFS.The optimum experimental parameters,the effect of coexistent elements on the determination of arsenic, antimony,bismuth,selenium,tellurium ,the accuracy and precision of the method are investigated. |
