摘要
本文采用电感耦合等离子体质谱法同时测定生活饮用水中As、Se、Pb、Cd、Be、Mo、Ni、Ag、Sb、Tl、Na、Al、Fe、Mn、Cu、Zn、B和Ba。18种元素的检出限在0.0040~6.0600μg·L^(-1),均符合各元素标准最低限值要求,线性范围宽,线性关系好,相关系数均大于0.9995。测定18种元素的相对标准偏差为0.30%~3.95%,各元素的加标回收率为89.5%~108.0%。结果表明该方法简便高效、灵敏度高、重现性好,适用于饮用水中18种元素的同时测定。
Inductively coupled plasma mass spectrometry was used to simultaneously determine As,Se,Pb,Cd,Be,Mo,Ni,Ag,Sb,Tl,Na,Al,Fe,Mn,Cu,Zn,B and Ba in drinking water.The detection limit of 18 elements is 0.0040~6.0600μg·L^(-1),all meeting the minimum limit requirements of each element standard.The linear range is wide,the linear relationship is good,and the correlation coefficient is greater than 0.9995.The relative standard deviation for the determination of 18 elements is 0.30%~3.95%,and the recovery rates for each element are 89.5%~108.0%.The results indicate that this method is simple,efficient,sensitive,and reproducible,and is suitable for the simultaneous determination of 18 elements in drinking water.
