Hydride-atomic fluorescence spectrometry antimony pounds and antimony trioxide of arsenic
Abstract: to establish a hydride-atomic fluorescence spectrometry antimony pounds and antimony trioxide arsenic in the new method. Samples by strong acid dissolution after completely, the sodium hydroxide matrix trace arsenic antimony precipitation and separation to 20% (V/V) for the determination of hydrochloric acid medium, in atomic fluorescence spectrometer on the arsenic determination, separation effect is good, the determination results stability. Methods of detection limit for 0.156 ng/mL, relative standard deviation (n = 11) of 1.12%.
