全自动红外测油仪测定水中油的萃取剂研究
|
摘要
使用全自动红外测油仪测定水体中的油类物质,选用测油专用的四氯化碳和化学纯的四氯乙烯作为萃取剂进行了对比。结果表明,以四氯乙烯为萃取剂,方法的检出限、准确度和精密度与四氯化碳作为萃取剂时接近,能够达到全自动红外分光光度法测定水中油类的方法要求,四氯乙烯可以成为四氯化碳的替代试剂。
Automatic IR oil analyzer was used to determine oil in water.Carbon tetrachloride for oil determination and chemically pure tetrachlorethylene were used as extracting agents to extract the oil in water for comparison.Results showed that the detection limit,accuracy and precision of the method with tetrachlorethylene 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.Tetrachlorethylene could be used as a substitute of carbon tetrachloride to extract oil in water for automatic IR oil analyzer.
