电感耦合等离子体原子发射光谱法测定铜阳极泥中8种元素

以盐酸和硝酸溶解样品，采用电感耦合等离子体原子发射光谱法（ICP-AES）测定了铜阳极泥中铜、铅、硒、锑、铋、砷、铁、镍8种元素的含量。对取样量、试样的溶解、测定介质、分析谱线选择等测定条件进行探讨。在优选的条件下进行测定，基体和共存元素对被测元素没有干扰，不需要进行预分离。各元素校准曲线的线性范围：Cu为0～50 μg/mL，Pb、Se为0～20 μg/mL， Sb、Bi、As、Fe、Ni为0～10 μg/mL。校准曲线相关系数在0.999 1～0.999 9之间。该法已用于生产和经营中铜阳极泥样品的分析，样品的测定结果与化学法吻合，加标回收率为97.1%~106.8%，相对标准偏差在0.37%~2.7%之间。

Determination of eight elements in copper anode mud by inductively coupled plasma atomic emission spectrometry

The content of eight elements including copper,lead,selenium,antimonium,bismuth,arsenic,iron and nickel in copper anode mud sample were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES) after dissolution of sample with hydrochloric acid and nitric acid.The determination conditions,such as sampling amount,sample dissolution,medium and the selection of analytical lines,were discussed.Under the optimized conditions,the matrix and coexisting elements had no interference in the deter...
