摘要
使用ICP-MS同时检测水样中18种元素,18种元素的线性相关系数最低0.9996,方法检出限为0.02-1.09ng/mL,多次平行测定的RSD均低于5%,加标回收率在95.47%-114.67%,方法线性关系良好且检出限低、精密度和准确度高。
In this study,a new method to determine 18 elements concurrently in water sample was found by ICP-MS.Results show that every linear correlation coefficient of 18 elements is over 0.9996,and RSD are all less than 5%.Method detected limit is in the range of 0.02-1.09 ng/mL.The recovery is in the range of 95.47%-114.67%.
