摘要
采用有机改性溶胶_凝胶制备技术 ,以四甲氧基硅烷 (TMOS)和二甲基二甲氧基硅烷 (DiMe_DiMOS)为共先驱体包埋聚苯乙烯磺酸钠 (PSS) ,通过离子交换成功地将联吡啶钌固定在玻碳电极表面。电化学研究结果表明 ,被固定的联吡啶钌保持了良好的电化学活性 ,同时该方法制备的修饰电极对甲基安非他明有灵敏的电化学响应。
In this paper, organic modified sol-gel preparation technique was applied to embed poly-sodium 4-styrenesulfonate (PSS), using TMOS and DiMe-DiMOS as co-precursors and then it was successfully immobilized Ru(bpy) 3 2+ on the surface of glass carbon electrode via ion-exchange. The data from electrochemistry experiments showed that the immobilized Ru(bpy) 3 2+ maintained its electrochemistry behaviors very well and the modified glass carbon electrode prepared in this method presents high sensitivity to methamphetamine.
