摘要
建立了应用百里酚兰（Ｔ．Ｂ）──亚甲基兰（Ｍ．Ｂ）混合指示剂测定碳酸氢铵母液中的烷基磺酰氯（活性物）含量的新方法，通过加入过氧化氢排除了硫化物干扰，方法的回收率９６％～１０３％，对实际样品测定相对标准偏差（Ｒ．Ｓ．Ｄ）≤３．３％。
A new determination method of the alkyl sulfonyl chloride in the ammoniun acid carbonate mother solution is established by using thymol blue-methene blue mixed indicator.The interference of sulphide is removed by peroxide of hydrogen.The recovery of the method is 96-103% R.S.D≤3.3%(n=5).
