摘要
采用硝酸－高氯酸消解、氯化亚锡还原光度法检测液体洗涤剂中总磷含量，从而建立了液体洗涤剂中微量总磷分析方法。此方法操作简单、准确、快速，方法最低检出限ＤＬ＝０．００６ｍｇ／Ｌ，加标回收率１０３％，精度＜５％。该方法既有学术价值又有实用价值。
In this paper, the content of total phosphate in two kinds of liquid cleansers was determined by stannous chloride method. The samples were digested with HNO3-HClO4 before colorimetric determination of P.This method gained DL=0.006mg/L,CV=2.7%, The recovery of known sample was 103%. This method increases analytical speed and operates simple.
