| 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. |
