近年来,在电分析方面,修饰电极的研究领域十分活跃。为提高电极的灵敏度,各种修饰电极相继出现,如碳糊电极、涂层电极及共价键合型修饰电极等。这些修饰电极,大多是在原有电极如玻碳电极上进行物理涂敷或化学处 In recent years, in the field of electrical analysis, the research field of modified electrodes is very active. In order to improve the sensitivity of the electrodes, a variety of modified electrodes appear one after another, such as carbon paste electrodes, coated electrodes and covalently bonded modified electrodes. These modified electrodes, mostly in the original electrode such as glassy carbon electrode for physical coating or chemical
