摘　　要：介绍了一种测定油田化学剂中总氯含量的新方法.该法用氢氧化钠-乙醇溶液将有机氯转变为氯离子,采用电位滴定法测定不同类型油田化学剂中的总氯含量.该方法的测量范围为0.50μg/g^0.5 g/g,具有分析成本低、操作简单、准确度高及重复性好的优点.A new technique for the determination of total chloride in oilfields chemical agents was introduced.In this technique,organic chloride was converted into chloride by using sodium hydroxide and ethanol,and total chloride detected using potentionmetry.It could detect total choride in the range of 0.50 μg/g～0.5 g/g,and it also had some advantages,such as low cost,simple,high precision and good repeatability.
