摘　　要：采用氯化银比浊法对潲水油中微量氯离子进行了测定，分别探讨了波长、酸度、稳定时间、样品处理条件对测定结果的影响。结果表明，最佳实验条件为：检测波长400nm，线性范围0．16～4μg／mL，加标回收率为97％-103％，相对标准偏差均小于5％。该法准确、快速、简便，可以作为快速鉴别潲水油的方法之一。Trace chlorine ion in hogwash oil was determined by silver chloride turbidimetry. The effects of measuring wavelength, acidity, stabilization time, sample treatment conditions on determination results were studied. The results showed that the optimal analysis conditions were as follows：the determination wavelength 400 nm,the linear range 0.16 - 4 μg/mL,the recovery rate 97%- 103% ,the relative stand- ard deviation less than 5 %. The experimental method was accurate and simple, and it could be one of the methods to quickly identify hogwash oil.
