摘　　要：本文模拟人们喝水习惯,将沸腾的饮用水倒入一次性塑料杯中,自然冷却后采用正己烷萃取,气相色谱-质谱法测定浸出液中16种邻苯二甲酸酯(PAEs)含量。结果表明:在方法检出限0.02-0.05mg/L下,20种不同品牌的塑料杯浸出液全部检出PAEs,总量为0.102-0.288mg/L,检出率100%,检出含量最高的是DIBP,但检出量均为超过《食品容器、包装材料用添加剂使用卫生标准》(GB 9685-2008)中规定的1.5mg/kg,总体看来,16种PAEs的迁移存在差异,分子质量大的PAEs迁移率低于分子质量小的PAEs。This paper mainly focused on phthalic acid esters（PAEs） migration from disposable plastic cups to drinking water. Hot water was transferred into disposable plastic cups, then n-hexane was used as solvent to extract PAEs from water after cooling down. Concentrations of 16 PAEs was detect by GC-MS. Results indicate that all 20 disposable plastic cups contained PAEs, the range was from 0.102 to 0.288mg/L, DIBP was the main species of PAEs. The content of all detected PAEs were exceed the standard（1.5mg/kg） based on national standard（GB9685-2008）. Overall, migration rate of all PAEs from disposable plastic cups were different, the migration rates of higher molecular weight PAEs were lower than those small molecular PAEs.
