| Abstract: | Study on As, Hg, and Se by Hydride Generation-Atomic Fluorescence Spectrometric. The reducing agent is KBH4-NaOH, and the liquid is 5% HC1. The correlation coefficient of standard curves are greater than 0. 999; The detection limits are less than criterion of detections; RSD are less than 5%; The result of certified reference materials get to request; The result of Recovery of the method is 90%-100%. The method that applied for determining As, Hg, and Se in water has so many advantages, such as simple, accurate and rapid. |
