| Abstract: | A flow injection analysis system with hydride generation spectrophotometric detection was designed for the determination of trace arsenic. This flow injection analysis system is no need for any carrying gas. The hydride generator and the absorbing device were made by ourself. The mixing solution of nitric acid-silver nitrate-polyvinyl alcohol-ethanol was used for the absorption of arsenic hydride. The conditions of arsenic detection were studied. The main advantage of this method is simple equipment, easily operating, rapidly determining (30samples/h) less consuming, and high sensitivity. In addition, the good reproducibility was obtained and the linear range is controllable. |
