摘要
建立了氯丙烯氧化液油相中双氧水含量的测定方法。考察了硫酸溶液的用量、碘化钾溶液的用量及萃取后静置时间等条件对双氧水含量分析的影响。结果表明，最佳分析条件为样品用水萃取后，依次加入硫酸溶液、碘化钾溶液、4滴钼酸铵溶液，用硫代硫酸钠标准溶液滴至近终点。该方法准确、快速、灵敏，测定的相对标准偏差为0．69％-1．58％，回收率为91．7％-102％。
To establish a method for determination of H2O2 in allyl chloride oxidation liquid oil-phase. The effects of the amount of sulfuric acid solution, the amount of potassium iodide solution and quiescent time after extraction were investigated. Optimal analytical condition was obtained are that：the sample was extracted with water, then added sulfuric acid solution,potassium iodide solution, and four drops of ammonium molybdate. The subsequent sample solution was titrated with sodium thiosulfate standard solution, the results shows that：the relative stardard deviation is 0.69% - 1.58%. The recovery is 91.7% - 102%. This method is accurate, quick and has good sensitivity.
