摘　　要：研究了在70℃和90℃下,采用直接浸泡法使白卡纸中的固化剂二苯甲酮（BP）和1-羟基环己基苯基甲酮（HCH）向水、3%乙酸、15%乙醇、50%乙醇、95%乙醇等食品模拟物质迁移,采用高效液相色谱仪（HPLC）分别检测迁移后模拟物质中的迁移量。结果表明两种固化剂在0.64~40mg/L的质量浓度范围内呈良好线性,相关系数不小于0.9995。温度越高,迁移时间越长,迁移量也越大;随着乙醇浓度的增高,BP、HCH的迁移量也增加;对于3%乙酸,BP和HCH迁移率最小。The migration of Benzophenone（BP） and 1-Hydroxycyclohexyl phenyl ketone（HCH） from paper into water,3% acetic acid,15% ethanol,50% ethanol and 95% ethanol was studied using the direct immersion method at 70℃ and 90℃ respectively. High performance liquid chromatography（HPLC） was developed for the detection of BP and HCH in these food simulants, The calibration cures of 2 photoinitiators were liner in the range of 0.64-40mg/L with correlation coefficients not less than 0.9995. The migration was more significant at higher temperature and longer migration time. At the same time,the migration of both BP and HCH increased more sharply with higher concentration of ethanol. The migration in 3% acetic acid was less than other food simulants.
