    摘要:

    了解我国仿瓷餐具中三聚氰胺和甲醛迁移情况以及两者迁移是否存在关联,为以后进行危险性评估奠定基础。方法 采用分光光度法测定模拟物中甲醛的迁移量,高效液相色谱法测定模拟物中三聚氰胺的迁移量,迁移实验条件为90℃,30min,模拟溶剂为3%乙酸。结果41个样品中,有28个样品检出三聚氰胺,其中最大值为0.85mg/dm2,最大迁移量约为欧盟限量标准的17.0%,所有样品的三聚氰胺迁移量均未超过欧盟的限量值;41个样品中,全部检出甲醛,其中最大迁移量为270.56mg/dm2,约为欧盟限量标准的108.2倍,有22个样品超过欧盟的特定迁移量规定,超标率达53.66%;41个样品中有27个样品甲醛与三聚氰胺的迁移量的比值大于6,最大比值为10033.0,是文献中所提供最大比值6的2090.2倍。 结论仿瓷餐具中甲醛的迁移值异常高而三聚氰胺的迁移量为未检出时,其不为三聚氰胺-甲醛(密胺)餐具的可能性极大。目前市售的仿瓷餐具的安全性值得进一步的关注。

    Abstract:

    To investigate the migration and correlation of melamine and formaldehyde from melamine tableware in China markets, and to provide the scientific basis for future risk assessment. Methods Migration of formaldehyde was analyzed by spectrophotometric and migration of melamine was analyzed by HPLC. Migration experimental conditions were 90degree for 30minutes, and the analog solvent was 3% acetic acid. [WT5"HZ]Results 41samples were collected from markets. Melamine was detected in 28samples and the maximum migration value was 0.85mg/dm2. It was about 17.0% of SML regulated by EU. Formaldehyde was detected in all 41samples. The maximum migration value was 270.56mg/dm2. It was about 108.2times SML regulated by EU. 53.66% of samples exceeded the SML value. Conclusion If melamine wasn’t detected but high amount of formaldehyde was detected, then the tableware might not be melamine tableware. The safety of melamine tableware is worthy of further attention.
