Use Of Surfactant In The Determination Of Arsenic By Flow Injection Hydride Generation Atomic Absorption Spectrometry, Julian Tyson, Robert Ellis

Chemistry Department Faculty Publication Series

The possible benefits of the addition of an anionic surfactant, didodecyldimethylammonium bromide, in the determination of arsenic, by flow injection hydride generation atomic absorption spectrometry using a flame-heated quartz tube atomizer, were studied in the light of previous reports concerning the effects of surfactants on chemical vapor generation procedures. Concentrations of arsenic between 5 and 30 μg 1-1 were used. Calibrations in the presence and absence of the surfactant in the sample solution were not significantly different, either for the case where vesicles were formed in the presence of the analyte or where they were preformed in the surfactant solution …
