| Abstract: | The determination of the trace element Cu in Kushen was performed by ultraviolet-visible spectrometry, and compared with flame atomic absorption spectrometry. The results showed that the average recovery rate with standard addition mode of these two methods were 93. 2% and 102. 5%,and the relative-standard deviations for the determination were 1. 82% and 1. 18%. The method of ultraviolet-visible spectrometry is simple and reliable and can be used in the determination of practical samples. |
