英文摘要	建立了高分子聚合物螯合-超滤(PCP-uf)分离富集、电感耦合等离子体质谱(ICP-MS)测定海水中痕量金属元素的方法。海水中的Cu2+,Pb2+,Cd2+,CO2+,nI2+等金属离子与聚乙烯亚胺(PEI)形成高分子螯合物,经超滤截留、酸解离后,实现金属离子从海水中定量分离、富集。ICP-MS采用全定量数据采集模式、内标校正的标准校正曲线法进行定量分析。在最佳条件下,方法的相对标准偏差(rSd)在3.4%(Cd)~9.3%(Pb)之间(0.20μg/l,n=5),标准加入回收率为78.7%(Ag)~95.2%(Cu);检出限(dl,10&)为1.2 ng/l(Cd)~9.8 ng/l(Cu),空白为1.1 ng/l(Cd,Ag)~9.1 ng/l(Cu)。本方法可应用于近岸及河口海水样品中痕量金属元素的同时测定。; A method using polymer-complexation and ultrafiltration for matrix modification and inductively coupled plasma mass spectrometry(ICP-MS) for determination of trace level of metal elements(Cu2 +,Pb2 +, Cd2 +,Ni2 + and Ag +) in coastal and estuarine seawater has been developed.Full quantitative data collection mode and internal standard calibration curve were used for ICP-MS measurement.Under optimized conditions, the relative standard deviations(RSDs) were lower than 9.3%(0.20 μg/L,n = 5),and the standard added recoveries were 78.7%-95.2%.Detection limits(10 &) were from 1.2 ng/L(Cd) to 9.8 ng/L(Cu).The method blank ranged from 1.1 ng/L(Cd,Ag) to 9.1 ng/L(Cu).The developed method has been applied to simultaneously determine the metals in coastal and estuarine seawater.; 厦门大学近海海洋环境科学国家重点实验室自主创新项目(No.MELRI0703)资助
