浅析乳胶制品中天然乳胶含量的测定方法

Analysis on the determination method of natural latex content in latex products

天然乳胶含量的测定是判别乳胶制品质量的重要指标,也是消费者最为关注的指标。由于乳胶制品成分复杂,仅采用单一的分析手段无法准确地测定天然乳胶含量,本文分析了多种仪器联用的手段来准确测定天然乳胶含量的方法 :热裂解气相色谱-质谱分析、红外光谱分析、X射线荧光光谱分析、热重分析、紫外-可见分光光度分析等多种分析手段的综合使用,结果的互相印证,有利于乳胶制品中天然乳胶含量的准确测定,为打击虚假宣传“纯天然乳胶”提供了数据支撑,对促进天然乳胶行业的健康发展具有重要意义。

The determination of natural latex content is an important indicator for judging the quality of latex products and is also the most concerned indicator for consumers.Due to the complex composition of latex products,it is not possible to accurately determine the content of natural latex using a single analytical method.This article analyzes the methods for accurately determining the content of natural latex using multiple instruments,including thermal decomposition gas chromatography-mass spectrometry,infrared spectroscopy,X-ray fluorescence spectroscopy,thermogravimetric analysis,and UV visible spectrophotometry.The mutual confirmation of results is conducive to the accurate determination of natural latex content in latex products,which provides data support for combating false advertising of"pure natural latex"and is of great significance for promoting the healthy development of the natural latex industry.
