离子选择性电极是近年来获得广泛应用的电化学传感器。特别是到六十年代中期,由于化工领域中有机合成和无机单晶拉制技术的发展,给寻找新的离子选择性电极开拓了广阔的途径。短短十几年,混晶陶瓷膜、液膜、气敏和酶膜电极等采用新材料、新工艺制成的各类电极先后出现,又促进了离子选择性电极理论研究和应用的开展,并取得了丰硕成果,成为七十年代分析化学领域中与气相色谱、原子吸收光谱一样,是发展较快的一门新技术。现有的商品离子选择性电极,国内外已达30余种,可以直接或间接测定50多种离子并应用于各个
Ion selective electrodes are widely used electrochemical sensors in recent years. Especially by the mid-1960s, due to the development of organic synthesis and inorganic single crystal drawing technology in the field of chemical industry, it has opened up a broad way for finding new ion-selective electrodes. In just a dozen years, all kinds of electrodes made of new materials and new processes such as mixed ceramic ceramic membrane, liquid membrane, gas sensor and enzyme membrane electrode appeared in succession, which promoted the theoretical research and application of ion selective electrode. Has achieved fruitful results, as in the seventies analytical chemistry and gas chromatography, atomic absorption spectroscopy, is the rapid development of a new technology. The existing product ion selective electrode, has reached more than 30 kinds at home and abroad, can be measured directly or indirectly more than 50 kinds of ions and applied to each
