摘要
建立了固相萃取(SPE)-红外分光光度测定水中总油的方法,并对固相萃取条件进行了优化,实验表明,对于1L添加2mg标准油的水样,其总油的回收率为86%-93%,多次重复实验测定的相对标准偏差为2.9%(n=6)。
A method for the determination of total oil in the water by SPE-Infrared Spectrophotometry was developed.The operation parameters of SPE were optimized.The accuracy of the proposed method was tested by recovery measurements on spiked samples,and good recovery results(86%-93%)were obtained,the relative standard deviation was 2.9%.
