| Abstract: | In this paper,the meassuring conditions of atom trapping method and the influence of medium on atom trapping are researched. Micro copper in human hair is successfully determined. The sensitivity of the determination of copper by atom trapping is 7. 7 times higher than that by conventional AAS method. The recovery is 94. 4%-100. 4 %. |
