为履行“国际公约”改进红外法测定水中油萃取技术探讨

To fulfill "the Convention",improve extraction technology for infrared method determining oil in water

四氯化碳是国际公约《关于消耗臭氧层物质的蒙特利尔议定书》确定为全球禁止使用的试剂,为此,四氯化碳作为红外法测定水中油的萃取剂应逐步被低毒和环保的试剂所取代,国外已在测定方法和萃取剂取代两方面做了大量工作,这些经验可以为我们所借鉴。

Carbon tetrachloride is the reagent banned by The Montreal Protocol on Substances that Deplete the Ozone Layer＂ in the world, carbon tetrachloride as extractant to be used in the infrared method for the determination of oil in water should be replaced gradually with other low toxicity and more environmentally friendly reagents. Some countries have been done a lot of work in both testing method and replacing the extractant. These experiences may use for reference for us.
