目的：建立了电感耦合等离子体质谱法（ ICP-MS）同时测定饮用水中铝、铜、锌、硒、砷、汞、镉、铅、铁、锰、钼、锡、铍、锑、镍、钡、银、铬、铊等19种金属元素含量的快速检测方法。方法对仪器工作参数进行优化，选取7 Li，45 Sc，72 Ge，115 In，209 Bi作为测定元素的内标元素，有效克服了基体效应、接口效应及仪器波动所产生的影响，利用八极杆碰撞/反应池技术，消除多原子离子对待测元素的干扰。结果19种金属元素在测定的含量范围内标准曲线线性关系良好，相关系数都在0.9992以上，方法检出限为0.002～0.444μg/L，定量限为0.006～1.480μg/L，低、中、高含量水样加标回收率为85.9％～105.5％，相对标准偏差（ RSD）为0.60％～5.65％（ n＝6）。结论该法具有操作简便、干扰少、分析速度快、灵敏度高、结果准确可靠等优点，是测定饮用水中金属元素含量的理想方法。
