| 摘 要： | 利用离子液体为粘合剂制作碳糊电极,采用高分子聚合法,合成包埋有Ru(bpy)2(dcbpy)2+的高分子聚合物,将钌聚合物掺杂于离子液体碳糊电极中,制作电化学发光传感器.结果表明,此传感器具有很好的电化学发光特性,与用石蜡油为粘合剂制作的电化学发光传感器相比,离子液体为粘合剂的电化学发光传感器检测三丙胺的检出限降低1个数量级.海洛因对电化学发光传感器的发光信号有很好的增强作用,基于此建立了高灵敏度检测海洛因的电化学发光分析法,海洛因浓度与电化学发光信号在2.0×10-9～2.0×10-5 mol/L范围内呈良好的线性关系,检出限为8×10-10 mol/L (S/N=3).将电化学发光传感器在5.0×10-9 mol/L海洛因溶液中采用线性循环电位连续扫描60圈,相对标准偏差小于2.2%.本方法用于血清中海洛因的检测,其回收率为94%～101%.

| Abstract: | An electrogenerated chemiluminescence ( ECL) sensor was fabricated by employing ruthenium complex polymer as ECL signal and ionic liquid as binding reagent and a sensitive ECL method for the determination of heroin was developed. The ECL sensor was prepared by thoroughly mixing ruthenium complex polymer,graphite powder and ionic liquid,which shows good electrochemical and ECL behaviors. The detection limit for tripropylamine ( TPA) was one order of magnitude lower than that observed at the paraffin modified... |
