| Abstract: | An improved method for determination of As, Sb and Hg in geochemical samples by Hg- AFS is reported. The samples are dissolved with aqua regia. The solution is added with Victim C and thiourea, then with tartar. As, Sb and Hg in the solution can be determined directly by HG -AFS, and As and Hg may be determined simultaneously. The detection limit, accuracy and precision for the method are in agreement with the needs of the-document . |
