摘要
碲化铜物料成分复杂,金含量变化较大。试验提出了泡沫塑料富集、原子吸收光谱法测定碲化铜中金含量的分析方法。结果表明,金的质量浓度在0~100μg/m L范围内,与发射强度呈良好的线性关系,相关系数为0.999 9;方法检出限为0.022μg/m L。实验方法用于测定,测定结果显示,相对标准偏差(RSD)低于5%,回收率为98%~103%。
The composition of copper telluride material is complex and the gold content changes greatly. A method for the determination of gold in copper telluride by atomic absorption spectrometry after enrichment with foamed plastics was proposed. The results show that the mass concentration of gold is 0 ~ 100 μg/m L. There is a good linear relationship with emission intensity in that range, and the correlation coefficient is 0.999 9. The detection limit of the method was 0.022 μg/m L. The relative standard deviation(RSD) of the results is less than 5% and the recovery is 98% ~ 103%.
