高效液相色谱法测定三聚氰胺——甲醛食品容器中三聚氰胺单体迁移量

Determination of Melamine Monomer's Migratory Quantity from Melamine-Formaldehyde Products used as Containers by High Perfomance Liquid Chomatography

本研究采用高效液相色谱法(HPLC)[1-4]测定三聚氰胺-甲醛食品容器中三聚氰胺单体迁移量。样品采用常规直接浸泡法[5]、微波条件浸泡法两种不同前处理方式后直接通过高效液相色谱仪分析三聚氰胺单体迁移量。结果表明常规直接浸泡法(酸性条件)、微波条件浸泡法(酸、水、醇条件)均有三聚氰胺单体迁移出。两种浸泡方法比较:三聚氰胺单体的迁移量微波法高于普通浸泡法。

This paper studied the determining of melamine monomer＇s migratory quantity from melaine-formaldehyde used as containers by high performance liquid chromatography. After pretreated with two different ways which are normal immersion method and microwave immersion method, the melamine monomer＇s migratory quantity of the sample was determined by HPLC. It is demonstrated that melamine monomers migrate from the sample, which two pretreated method were normal direct immersion method （acid condition） and microwave immersion method（acid, waster, alcohol condition）. It is also showed that migratory quantity of melamine monomer from sample pretreated with microwave method is more than conventional immersion method.
