本文以人体模拟液和水为萃取剂,分析纸巾中荧光增白剂在人体模拟液和水中的迁移现象.以荧光增白剂VBL为标准物质配制标准溶液并绘制标准曲线,用紫外分光光度法测出其最大吸收波长为 348 nm.本文分别研究了人工酸性汗液、人工碱性汗液、人工尿液、人工唾液和水 5 种溶液中荧光增白剂的检测方法,检测得到相关系数R2 均大于 0.999,检出限在 0.43~0.98 μg/g之间,回收率均超过 80%,精密度相对标准偏差(RSD)均小于 10%.经方法评估,本文建立的荧光增白剂VBL的紫外分光光度定量分析方法简单实用,且具有良好的准确度.
Determination of Migration Amount of Fluorescent Whitening Agents in Tissue Paper in Simulated Body Fluid
This study investigated the migration of fluorescent whitening agents from tissue paper into simulated body fluids and water using these as extractants.Standard solutions were prepared using the fluorescent whitening agent VBL as a reference material,and standard curves were plotted.The maximum absorption wavelength of VBL was determined to be 348 nm using UV spectrophotometry.The study developed and evaluated the detection methods for fluorescent whitening agents in five different solutions:artificial acidic sweat,artificial alkaline sweat,artificial urine,artificial saliva,and water.The methods demonstrated high correlation coefficients(R²>0.999),detection limits ranged from 0.43 to 0.98 μg/g,recoveries exceeded 80%,and the relative standard deviations(RSDs)for precision were all below 10%.The UV spectrophotometric method established for the quantitative analysis of the fluorescent brightener VBL was found to be straightforward,practical,and accurate.
