摘　　要：采用智能测硫仪,使吸附在活性炭上的有机硫在高温空气流中燃烧、分解,定量地转化为二氧化硫,用库仑滴定法测定。水中无机硫化物的干扰用乙酸铜均匀沉淀法去除。In this article, we determined adsorbable organic sulfide in water with the instrument for determining sulfur in coal. At first, adsorbable organic sulfide in water was adsorbed on active carbon,and then the active carbon was placed into the instrument. Adsorbable organic sulfide was translated into sulfide dioxide under the high temperature and oxygen, so it was determined by Coulomb titration. In this method the interference come from inorganic sulfide was removed by Copper acetate homogenous precipitation method.
