摘　　要：目的:建立电感耦合等离子体质谱(ICP-MS)测定饮水材质内壁涂料中16种元素含量的方法。方法:采用ICP-MS同时测定饮水材质内壁涂料中Al、As、Ba、Zn、Cu、Sb、Cr、Ni、Fe、Mn、Cd、Pb、Ag、Se、Sn、Be等16种元素。结果:实验表明,方法的线性相关系数均>0.999,检出限0.005μg/L～0.288μg/L,加标回收率均在86.5%～118.0%之间,测定质控样品,测定值均在标准值范围内。结论:该方法简便、快速、灵敏、准确,适用于饮水材质内壁涂料中16种金属元素的同时测定。Objective： To establish a method for simultaneous determination of 16 elements contents in soaking water of dope on material walls for drinking water by ICP - MS. Methods： Sixteen elements including Al, As, Ba, Zn, Cu, Sb, Cr, Ni, Fe, Mn, Cd, Pb, Ag, Se, Sn, Be in soaking water of dope on material walls for drinking water could be determined by ICP - MS. Results： The result showed that the linear correlative coefficient was higher than 0. 999, the recovery rate ranged from 86.5 % to 118.0 % and the result was satisfying when compared with standard sample. Conclusion： The method is simple, rapid, sensitive and accurate and can be applied to the simul- taneous determination of 16 elements in soaking water of dope on material walls for drinking water.
