高纯氯化锂中微量铜、锌、铁、锰的测定-Tritonx-100增感原子吸收光谱法

Determination of Micro-amounts of Copper、Zinc、Iron、Manganese in Pure Lithium Chloride

采用Tritonx-100为铜、锌、铁、锰的增感剂,对高纯氯化锂中的铜、锌、铁、锰进行了原子吸收光谱分析,结果令人满意。其特征浓度铜为0．018μg．ml-1／1％吸收、锌为0．004μg．ml-1／1％吸收、铁为0．021μg．ml-1／1％吸收,锰为0．011μg．ml-1／1％吸收。

Using Tritonx -100 as an sensitizing agent can increase significantly the absorbency for copper,Zinc,Iron, Manganese. The characteristic concentration of copper amounts to 0. 018μg. ml^ - 1/1% absorbility,of Zinc amounts to 0.004μg. ml^ - 1/1% absorbility, of Iron amounts to 0.021 μg. ml^ - 1/1% absorbility, of Manganese amounts to 0.011 μg. ml ^- 1/1% absorbility. The linear scope of copper is 0 -4.5μg/ml,of Zinc is 0 - 1.8μg/ml,of Iron is 0 -2.5μg/ ml, of Manganese is 0 - 3.0μg/ml. The correlation coefficient of copper is 0. 9998,of Zinc is 0. 9994,of Iron is 0. 9993,of Manganese is 0.9991.
