摘　　要：目的:对砂锅浸出液中的多种元素进行测定,以期了解各元素的溶出状况。方法:采用电感耦合等离子体质谱法对砂锅浸出液中的十三种元素同时测定。结果:浸出液中铅、镉、银、硒、砷、镍等元素的浸出量很低,而锌、铜、铬等元素有一定量的浸出,镁、铝、锰、铁等元素则有较大的浸出量;砂锅在酸性条件下,部分元素会持续溶出,溶出量不会随着浸出次数而明显减少;相对于乙酸基体而言,砂锅的水浸出液中元素含量较低。结论:在酸性条件下,砂锅中的部分金属元素会有较高的溶出,而且具有持续溶出的特性,可能污染食物对人体造成伤害;上述金属元素在水中的溶出相对较少,一般不会对健康造成影响。Objective：Through the determination to understand the exsolution condition of elements from leach liquor of casserrole.Methods： 13 elements from leach liquor of casserole were directly analyzed by ICP-MS simultaneously.Results： Pb Cd Ag Se Ni had a low level in leach liquor,Zn Cu Cr had a middle level in leach liquor,and Mg Al Mn Fe were found out having a high content in leach liquor;some elements can keep leaching from casserole in acidic condition and the content in leach liquor can hardly reduce sharply with the repeated extraction.relative to acidic condition,the elements can be hardly found out in neutral condition.Conclusion： In acidic condition,the elements had a high content in leach liquor and can keep leaching from the casserole,some of which can hurt the human body.But the elements can be hardly found out in neutral condition and won′t harm the health.
