六氯四氟丁烷替代四氯化碳为萃取剂检测水中石油类的研究

Study on Detection of Oil in Water with Extraction Agent of S-316 Instead of Carbon Tetrachloride

使用红外分光光度法对水体中的石油类进行检测,通过对两种萃取剂四氯化碳和六氯四氟丁烷进行对比。结果表明:以六氯四氟丁烷为萃取剂,其方法的检出限、准确度和精密度与四氯化碳为萃取剂时十分接近,完全能够达到红外分光光度法测定水中石油类的方法要求,六氯四氟丁烷可以成为四氯化碳的替代试剂。

Infrared spectrophotometry was used to determine oil in water. Carbon tetrachloride and S-316 were used as extracting agents for comparison to extract the oil in water. Results showed that the detection limit,accuracy and precision of the method with S-316 as extracting agent matched those with carbon tetrachlorides as extracting agent and met the determination requirements of automatic analysis of oil in water depended on infrared spectrophotometry. S-316 could be used as a substitute of carbon tetrachloride to extract oil in water.
