| Abstract: | Microwave digestion-continuous flow hydride generation with hydrofluoric acid-AFS method was proposed for the determination of As in antimony trioxide. The time of preparing sample was reduced and loss of volatile components were avoided. Working conditions of atomic fluorescence spectrometer, the experimental conditions of microwave digestion-hydride generation were optimized. The detection limit of the method was 0. 35ug/L and the RSD was less than 5%. The recoveries obtained were 91.2%-100.3%. |
