摘要
目前国标GB/T16488—1996测油以红外分光光度法为第一方法 ,该法用CCL4 作萃取剂。CCL4 是有毒、易挥发的有机液体 ,在地面水、生活污水和工业废水的测油项目中 ,CCL4 用量大 ,如何处理萃取过水样的CCL4 废液是每个监测、科研单位遇到的问题。本文以回收利用作为解决问题的基本方法 ,介绍了CCL4 废液的回收再利用情况及所遇到的问题 ,本法工作原理简单 ,操作简便 。
Now in China GB/T16488-1996 regards infrared spectrometry as the first method to determine oil centent.CCL4 is the extractant in this method.It is poisonous and volatile.In process of assay CCL4 is needed a large quantity.How to treat CCL4 waste liquid is a problem to every environmental Monitering Center station.The paper provided a way to recycle CCL4 from CCL4 waste liquid.It has strong utility and is easy to operate.
