摘　　要：碳糊电极(CPE)是一种广泛应用于电化学领域的新型电极。将石墨粉和粘合剂混合成均匀的碳糊,然后将其挤压进电极管中便制成了碳糊电极。具有制备方法简单、背景电流小、无毒、电位窗口宽等优点,但由于制备过程中加入了不导电的粘合剂而降低了检测灵敏度。因此,制备碳糊电极时常加入修饰材料以提高电极的电化学性能。概述了碳糊电极和化学修饰碳糊电极的发展、制备方法和应用,对制备电极的材料和修饰剂的选用进行了分析。概括了近些年来化学修饰碳糊电极在不同领域的应用。The carbon paste electrode(CPE)is a new type of electrode prepared by mixing graphite powder and binder to form a homogenous carbon paste,then filling them into an electrode tube.It is widely used in the field of electrochemistry owing to some unique advantages such as simple preparation process,low background current,non-toxic and wide potential window.Although CPE has many advantages,the presence of non-conductive binder in CPE lead to hinder electron transfer and reduce the sensitivity of the detection system.Therefore,the modified materials are often used to improve the electrochemical performance of CPE.This article reviews the development,preparation methods and application of carbon paste electrodes and chemically modified carbon paste electrodes,and the selection of materials and modifiers for electrode preparation are analyzed.The applications of chemically modified carbon paste electrodes in different fields in recent years are summarized.
