摘要
通过对水中壬基酚及其聚氧乙烯醚等的提取试验 ,发现回流萃取是提取水中半挥发性有机物的一种很有效的方法。对提取剂进行了选择 ,表明环己烷效果较好 ,具有较高的回收率和较好的重现性。为保证高沸点壬基酚聚氧乙烯醚加合物的回收率在 95 %以上 ,取 90min作为回流萃取时间。
ion experiment of nonyl phenol and polyvinyl ethyl chloride, the method of reflux extraction was founded to be a good way to abstract half volatile organic substance. Among abstractors, cyclohexane has a high recovery rate. In order to assure that the recovery rate of adduct of nonyl phenol and polyvinyl ethyl chloride was more than 95%, extraction time was 90 min. The advantage of reflux extraction was introduced.
