摘要
采用过氧化钠熔融试样 ,用盐酸调节试液酸度 ,对电感耦合等离子体原子发射光谱 (ICP AES)法同时测定铈矿中微量砷和锑进行了研究 ,考察了铈基体及共存元素 。
A method of determination of trace impurity elements arsenic and antimony in cerium ores by inductively coupled plasma atomic emission spectrometry was reported. The influence of spectral and non spectral interference of cerium matrix, coexistent elements, acidic degree, and media to the signal to noise ratio was investigated. The spectral conditions and matrix concentration were optimized.
