Abstract: A flow injection system is used to mix glycerol solution, containing 0.12 to 3.0 µg g-1 of As, with 1.1% NaBH4 solution (in 0.2 or 0.5 M NaOH) - 6 M HCl (10:49). The generated AsH3 is removed in a vapor - liquid flow cell and determined directly by ICP-AES at 193.7 nm, with Ar as carrier gas (0.39 l min-1). The calibration graph was rectilinear in the range 0.12 to 3.0 µg mL-1 of As with a coefficient of variation of 1.4%.
