摘　　要：对比了碱熔法和湿法消解两种不同的方法处理样品,用电感耦合等离子体-原子发射光谱法(ICP-AES)测定口香糖中的Ti、Mn、Al、Ca、As、Pb、Cd元素。并对结果比较好的湿法消解方法进行了加标回收实验,平均回收率在97.5%—102.5%之间。The contents of Ti,Mn,Al,Ca,As,Pb and Cd were measured by ICP-AES after the chewing gum digestion by alkali fusion method and wet digestion.The results of wet digestion were better,and the added standard recovery experiment was carried out,and the average recoveries were from 97.5% to 102.5%.
