近年来,环境污染监测颇受人们的重视,探讨水中微量成份分布状况,检出水中ppb级元素便成了分析工作者研究的新课题。为此,寻求一种预浓集方法和采用一种同时测定多元素的新技术是十分重要的。本文介绍一种国产树脂在新设计的交换装置下,各类水样经浓集,用原子吸收法可成功的连续测定ppb级多种痕量元素。实验与方法 In recent years, people pay more attention to environmental pollution monitoring, and discuss the distribution of trace elements in water. Detecting ppb-level elements in water has become a new topic for analysis workers. For this reason, it is very important to seek a preconcentration method and adopt a new technique for simultaneous determination of multiple elements. This article describes a domestic resin in the new design of the exchange device, all kinds of water samples by concentration, with atomic absorption method can be successfully continuous determination ppb level trace elements.
