氢化物发生-无色散原子荧光光谱法测定高纯阴极铜中砷、锑、铋、硒和碲

Determination of Arsenic,Antimony,Bismuth,Selenium,Tellurium in Higher Purity Copper Cathode by Hydride Generation Atomic Fluorescence Spectrometry

研究了在氨性溶液中，以镧盐为载体，共沉淀富集高纯阴极铜中杂质Ａｓ、Ｓｂ、Ｂｉ、Ｓｅ、Ｔｅ，使之与基体铜分离，用氢化物原子荧光光谱法测定。考察了测定的最佳条件、共存元素对测定的影响及方法的准确度和精密度。

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.
