摘要:
在含赖氨酸的磷酸盐缓冲溶液中，用循环伏安法在制备好的纳米二氧化钛壳聚糖玻碳电极上聚合聚赖氨酸薄膜，采用循环伏安法和示差脉冲法研究对甲基苯酚在聚赖氨酸/二氧化钛壳聚糖修饰电极上的电化学行为.实验结果表明：聚赖氨酸/二氧化钛壳聚糖修饰电极对对甲基苯酚的氧化具有良好的电催化作用，对甲基苯酚的浓度在6.0×10-6~1.0×10-4 mol/L范围内与峰电流呈良好的线性关系；检测限可达5.0×10-7 mol/L.该复合修饰电极可作为电化学传感器用于对甲基苯酚的含量测定及环境水体中实际样品的分析.
Abstract:
 A novel Poly(Lysine)/nano TiO2/chitosanmodified glassy carbon electrodes was fabricated.Polylysine film was prepared on nano TiO2/Chitosanmodified electrodes by cyclic voltammetry in phosphate buffer solution.The electrochemical behavior of pcresol on the poly(lysine)/nano TiO2/chitosanmodified glassy carbon electrode is studied by cyclic voltammetry.Experiment result shows that pcresol has good electrocatalytic activity on modified electrode and the peak currents of differential pulse voltammetry are linear to the pcresol concentrations over the range of 6.0×10-6—1.0×10-4 mol/L.The detection limit is 5.0×10-7 mol/L.
