【摘要】 将５，１０，１５，２０－四－（３－甲氧基－４－羟基苯基）卟啉钴（ＣｏＴＭＨＰＰ）修饰在玻碳电极表面，制备成对多巴胶等神经递质有高灵敏度响应的ＣＯＴＭＨＰＰ修饰电极．电极具有灵敏度高、响应快、稳定性好等特点．电极响应时间小于１０ｓ，儿茶酚类化合物的检测浓度为１０（－６）ｍｏｌ／Ｌ．更多还原

【Abstract】 The 5, 10, 15, 20-tetrakis (3methoxy-hydroxyphenyl) porphyrin cobalt is absorbed on the surface of the glassy carbon electrode to make a CoTMHPP modified electrode.The modified electrode has high sensitivity and good electrocatalytic oxidation towards catechols for each range of their responses, and the response time is less than 10 s. The electrode possesses characteristicsof high catalytic activity, fast response, goodstability and a long lifetime under the optimal operations.更多还原
