中文摘要：

电气化学的免职制作的一个高度敏感的安培计的磺胺嘧啶传感器 poly (钴 tetraaminophthalocyanine )(poly (CoIITAPc )) 在多围的碳 nanotubes-Nafion (MWCNTs-Nafion ) 的表面上，修改电极被描述。这个电极由联合 CoIITAPc， MWCNT，和 Nafion 的优点显示出很吸引人的表演。与赤裸的玻璃质的碳相比，电极(GCE ) 和 MWCNTs-Nafion 修改了电极， electrocatalytic 活动(CoIITAPc ) poly，极大地产生的涂的 MWCNTs-Nafion GCE 包括低氧化潜力，高当前的回答，和好犯规反的性能向磺胺嘧啶改进了电气化学的察觉。当与 0.17 mol/L 的察觉限制从 0.5 ～ 43.5 mol/L 增加磺胺嘧啶的集中时，在新修改电极上获得的磺胺嘧啶的氧化山峰水流线性地增加了。

英文摘要：

A highly sensitive amperometric sulfadiazine sensor fabricated by electrochemical deposition of poly（cobalt tetraaminophthalocyanine） （poly（Co II TAPc）） on the surface of a multi-walled carbon nanotubes-Nafion （MWCNTs-Nafion） modified electrode is described.This electrode showed a very attractive performance by combining the advantages of Co II TAPc,MWCNTs,and Nafion.Compared with the bare glassy carbon electrode （GCE） and the MWCNTs-Nafion modified electrode,the electrocatalytic activity of poly（Co II TAPc）-coated MWCNTs-Nafion GCE generated greatly improved electrochemical detections toward sulfadiazine including low oxidation potential,high current responses,and good anti-fouling performance.The oxidation peak currents of sulfadiazine obtained on the new modified electrode increased linearly while increasing the concentration of sulfadiazine from 0.5 to 43.5 μmol/L with the detection limit of 0.17 μmol/L.
