【摘要】 改进金属探针的制作方法,并对未覆膜的探针进行机械处理与化学活化处理。检测了未修饰s BLM成膜过程的CV特性变化、未修饰s BLM和I2修饰s BLM在不同浓度KI溶液中的CV响应。实验发现I2修饰的s BLM对I 的运载能力不足以使得CV曲线出现明显的氧化还原峰,但可以在氧化还原电位以下进行CV扫描,通过电流大小来判断I 浓度大小。更多还原

【Abstract】 The method of making a probe was improved and the metal of the probe was treated with an mechanical and chymic methods.The Current-Voltage characteristics of unmodified s-BLM has been tested during its formation,and that of unmodified s-BLM and s-BLM modified with iodine in different KI solutions were studied.It shows that there is no obvious redox current of s-BLM modified with iodine.But the concentration of I can be distinguished by the CV screening under the redox voltage.更多还原
