摘要/Abstract

摘要： 建立了流动注射进样法结合717型阴离子树脂富集柱在碱性条件下同时富集饮用水中的Al,Cu,Fe,Mn和Zn等5种微量金属元素的MPT全谱仪原子发射光谱测定的新方法.本法简单快捷,成本低,而且可消除Na,Ca和K等基体元素的干扰(包括光谱干扰).取8mL水样时,对Al,Cu,Fe,Mn和Zn的检出限(3σ)分别为17,0.27,2.0,4.3和9.8μg/L;相对标准偏差均小于5%(n=7);在检测范围内各元素测量线性良好.本法已成功应用于自制水样和实际自来水样的分析.

Abstract: A novel flow injection system with on-line preconcentration was developed for the determination of Al, Cu, Fe, Mn and Zn in drinking water by using a simultaneous microwave plasma torch atomic emission spectrometer(MPT-AES). The preconcentration column was packed with 717-anion exchange resin under alkaline conditions. The operating parameters were studied and optimized. The detection limits are 17, 0.27, 2.0, 4.3, 9.8 μg/L for Al, Cu, Fe, Mn and Zn, respectively, and the relative standard deviations are less than 5%(n=7). The new system was successfully applied to the analysis of lab-made water and tap water samples.
