摘　　要：建立了非抑制离子色谱法同时测定塑料食品接触材料中一乙醇胺(MEA)、二乙醇胺(DEA)、三乙醇胺(TEA)、三异丙醇胺(TIPA)、N,N-二乙基乙醇胺(DEAE)等5种醇胺类物质迁移量的方法。方法选用水、3%(m/V)乙酸、4%(V/V)乙酸、10%(V/V)乙醇、20%(V/V)乙醇、50%(V/V)乙醇、橄榄油、正己烷等8种物质作为食品模拟物,满足水性、酸性、醇类与脂类食品的模拟。在优化条件下,目标物检出限在0.03~2 mg/kg之间(S/N=3),加标回收率在84.1%~118.6%,精密度在0.92%~4.1%(n=6)之间。A novel non-suppressed ion chromatographic method was developed for the determination of ethanolamine （MEA）, diethanolamine （DEA）, triethanolamine （TEA）, triisopropanloamine （TIPA） and N, N-diethyletholamine （DEAE） which migrated from plastics food contact materials and articles. In order to represent alkaline, acidic, alcoholic and fatty food, samples were immersed in simulants H20, including 3% （m/V） acetic acid, 4% （V/V） acetic acid, 10% （V/V） ethanol, 20% （V/V） ethanol, 50% （V/V） ethanol, olive oil, and n-hexane. Under the optimum conditions, the limits of detection （LODs） were between 0. 03 and 2 mg/kg （ S/N = 3 ）. The recoveries were in the range of 84. 1% -118.6%, and relative standard deviations （RSDs） were from 0. 92% to 4. 1% （n =6）.
