Abstract: In this paper,the determination of S2- and SO32- in solution were investigated by gas generation MIPAES.In the reaction cell S2- and SO32- reacted chemically with H2SO4 and formed H2S and SO2,respectively.The H2S and SO2 generated were carried into the MIP and the emission intensity at 216.9 nm was recorded.Various experimental conditions for determining S2- and SO32- were studied.The detection limits for S2- and SO32- are 0.08μg and 0.25μg.respectively.Good precision(RSD<5%)were observed either for S2- or for SO32-.
