中文摘要：

探索了利用紫外分光光度法测定土壤悬浮液中五氯酚的方法。采用紫外可见分光光度计，选定在波长255．6nm处测定碱性土壤悬浮液中五氯酚的含量，所得线性回归方程为Y=0．0295X＋0．0017，相关系数r=0．9999，检测限为0．016mg／L。加标回收率为103％-130％，实验结果表明此法简单、快速，准确性较高。

英文摘要：

The new method to determine pentachlorophenol in soil suspension was studied. The ultraviolet spectrometer was used for determining alkaline pentachlorophenol in soil suspension at a wavelength of 255.6 nm. The linear regressive equation is Y =0. 029 5X ＋0.001 7 with a correlative coefficient r =0. 999 9. The detection of this method is 0. 016 mg/L and the recovery range is 103% - 130%. Its repetition and precision are very good. These data showed that the new method is fast, convenient and repeatable; this method would be suitable for measuring the content of pentachl study its environmental orophenol in soil and also helpful to control pentachlorophenol content in environment and behaviors.
