密胺餐具中三聚氰胺的迁移规律

On the Migration of Melamine in Melaminoplastic Tablewares

密胺餐具样品用乙酸溶液浸泡后,采用高效液相色谱法测定其中三聚氰胺的迁移量。考察了浸泡液的种类、浸泡温度、浸泡时间、样品尺寸、浸泡次数等参数对三聚氰胺迁移量的影响。试验结果表明:三聚氰胺的迁移量随溶液酸性、浸泡温度、浸泡时间的增加及样品尺寸的减小而增大;随浸泡次数的增多,每次浸出量递减。

The sample of melaminoplastie tableware was soaked with acetic acid, and melamine in the solution obtained was determined by HPLC. Conditions of kinds of soaking solution, soaking temperature, soaking time, size of sample and number of time of soaking were studied. It was found that the amount of melamine migrated increased with increase of acidity of solution, soaking temperature, soaking time and with decrease of size of sample. Furthermore, the amount of melamine soaked out from the tablewares in each soaking, decreased with the increase of number of time of soaking.
