Determination of Specific Migration of Fluorescent Whitening Agent in Napkin by Fluorescence Spectrometry
摘要
Abstract
The method based on fluorescence spectrometry for specific transfer of napkins to distilled water analogue was established.The analyzed objects removed from the napkin were transferred to the analog objects and the external standard method was used to quantify.The Fluorescent whitening agent had good linear relationship (R2 ＞ 0.999) between 0.01 ～ 0.5 mg/L.The recovery rates of the 3 spiked levels (25,50 and 100 μg) were between 97.9％ and 102.3％,and the detection limit was 0.0012 μg/dm2.The method was simple and rapid with high sensitivity,which was appropriate for the fast determination of the migration of fluorescent whitening agent in napkin.The census from 17 samples of 10 brands of paper napkins on the market showed that:the rate of positive sample was 41.2％,and the migration of fluorescent whitening agent in napkin was 0 ～0.0061 mg/dm2.关键词
