离子选择电极是近十几年来发展起来的一种新的测试电极。目前,随着科学技术的迅速发展,这类电极及其有关分析技术已在冶金、地质、土壤、海洋以及环境监测等各个领域中获得了广泛的应用。但由于电极性能的限制,在有机分析特别是药物分析方面的应用报导不多。为此作者对新的敏化电极——酶电极及其应用进行了试验研究。酶电极主要由骨架电极复盖含有能引起有机物(底物)反应而生成使电极响应的物质的一种酶层组成的。酶电极的制备一般采用可溶性酶套置法、酶涂层法或物理截留 Ion selective electrode is a new test electrode developed in recent ten years. At present, with the rapid development of science and technology, such electrodes and their related analytical techniques have been widely used in various fields such as metallurgy, geology, soil, oceanography and environmental monitoring. However, due to the limitation of electrode performance, there are few reports on the application of organic analysis, especially in drug analysis. To this end the author of the new sensitized electrode - enzyme electrode and its application were studied. The enzyme electrode is mainly composed of a skeleton electrode covering an enzyme layer containing a substance that causes the organic substance (substrate) to react to generate a substance that responds to the electrode. Enzyme electrode preparation generally use soluble enzyme set method, enzyme coating method or physical retention
