一、前言近十余年来,离子选择电极(ISE)已迅速发展成为分析化学中很繁荣的一个学科分支并在有机分析领域中获得了应用。1969年开始,出现ISE与有机元素微量分析这两门学科的结合,它在某些方面具有独特的优点,解决了有机元素微量分析中某些长期来未能圆满解决的问题。由于ISE的一些常用测定方法准确度不高,局限了它在有机元素微量分析中的应用,截止目前,发表的论文尚只涉及到氟、氯、溴、碘、硫、汞、铅与硒八个元素的有机微量分析。
I. Introduction For more than ten years, ion selective electrode (ISE) has rapidly developed into a very prosperous branch of analytical chemistry and has been applied in the field of organic analysis. Beginning in 1969, the combination of ISE and trace element analysis of organic elements has emerged that has unique advantages in some aspects and addresses some of the long-standing and unsolved problems in trace element analysis of organic elements. Due to the low accuracy of some commonly used determination methods of ISE, its application in trace element analysis of organic elements has limited its publication to fluorine, chlorine, bromine, iodine, sulfur, mercury, lead and selenium eight Organic elements of the micro-analysis.
