摘要: 用气体发生-MIPAES法测定了溶液中的S2-和SO32-.样品中S2-和SO32-同稀H2SO4作用,产生H2S和SO2,用Ar气将产生的气体带入MIP.在216.9nm处测定硫的发射强度,考察了各实验参数对测定S2-和SO32-的影响.S2-和SO32-的检出限分别为0.08μg和0.25μg.RSD小于5%.

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-.
