中文摘要:

      通过氧瓶燃烧法对试样进行前处理，用氯化银比浊法测定了含氯有机物中的氯离子含量.优化了测定条件，选择测定波长在450 nm，不加稳定剂，氯离子浓度在0.8～8.0 μg/mL时线性良好，相关系数r²=0.99988，方法回收率可达91.1%～118.6%.

英文摘要:

      The chlorine content in the sample, which was pretreated by the oxygen bottle combustion method, was determined by the turbidimetric method on an UV spectrophotometer. 450 nm was selected as the primary wavelength. The method showed a good linearity and repetition in the range of 0.8～8.0 μg/mL with a correlation coefficient of 0.999 88. The recovery was 91.1%～118.6%. The method is usable to determine the chlorine content in organic compounds.
