摘　　要：使吸附在活性炭上的有机硫化物在高温氧气流中燃烧、分解、定量地转化为无机硫的氧化物，经硼砂双氧水溶液吸收，生成硫酸根离子，用离子色谱法分离测定．可测定ＡＯＳ的范围为２５～１３３３μｇ／Ｌ，回收率为８６．６％，相对标准偏差小于１０％（ｎ＝３５）用该方法还可同时测定水中的可吸附有机氯．Abstract Organic sulphur compounds adsorbed by activated carbon are burnned and decomposed into oxides of inorganic sulphur in high temperature oxygen stream.The oxides are adsorbed by alkaline hydrogen peroxide(H_2O_2) solution and oxidized into sulphate which is separated and measured by lon-chromatography.The determination range:25～1333μg/L.The recovery range:83.8～93.1%.Relative standard deviation<10%.Not only AOS but alse Aocl can be determinated simultaneously.
