中文摘要: 建立了火焰原子吸收光谱法测定高铋铅中铜含量的方法。方法研究了多种溶样方法,最终采用硝酸-酒石酸溶解试样。方法在10%硝酸介质中以火焰原子吸收光谱法测定溶液中的铜量,加标回收率在99.35%~104.85%之间,相对标准偏差(RSD,n=7)小于3.5%。该方法操作过程简单,精密度高,回收率良好,能够较好的满足分析检测的要求。
Abstract:A method for the determination of copper content in bismuth-rich lead by flame atomic absorption spectrometric method is established in this paper. A variety of sample dissolving methods were studied, and finally the sample was dissolved by nitric acid tartaric acid. The copper content was determinated by flame atomic absorption spectrometry in 10% nitric acid solution. The recovery rate of the method was between 99.35%~104.85%. The results of precision experiments showed that the relative standard deviation (RSD, n =7) was less than 3.5%. The operation of this method has the advantages of simple operation, high precision and good recovery and can meet the requirements of daily analysis and testing.
