一、前言自本世纪初Cremer、Haber和Klemensienicz发明离子选择电极以来,如今该分析方法已成为分析化学领域内与气相色谱、原子吸收光谱一样是发展较快的一门新技术。广泛用于冶金、地质、化工、生理、农林、原子能等工业和环境检测、海洋调查、地震予报等各部门。 I. INTRODUCTION Since the invention of ion-selective electrodes by Cremer, Haber and Klemensienicz at the beginning of this century, the analytical method has now become a new technology in analytical chemistry that has developed rapidly, like gas chromatography and atomic absorption spectroscopy. Widely used in metallurgy, geology, chemical industry, physiology, agriculture, forestry, atomic energy and other industrial and environmental testing, marine surveys, earthquakes and other departments.
