A microwave digestion combined with inductively coupled plasma mass spectrometric(ICP-MS) method was established for the simultaneous determination of 24 elements(Li,Be,B,Al,V,Cu,Mn,Zn,Cr,Ni,As,Sr,Zr,Se,Mo,Ag,Cd,Sn,Sb,Te,Ba,Hg,Tl,Pb) in food packaging paper materials and 3 kinds of food simulants(water,4% acetic acid,10% ethanol).The migration behaviors of these elements were investigated.The samples were digested by microwave and then detected by ICP-MS,and the food simulants were detected without microwave digestion. Under the optimized experimental conditions,24 elements showed good linear relationships in the range of 0-1000μg/L, with the method detection limits(MLOD) of 0.0003-0.465mg/kg.The recoveries of these analytes at spiked levels of 1.0-1000mg/kg were in the range of 90.5%-125.3% with relative standard deviations of 1.2%-6.8%.This method is simple, sensitive and accurate, and is suitable for the research on determination and migration behavior of elements in food packaging paper materials, which could provide a scientific basis for the quality supervision of food paper packaging materials.
