3.2.1 循环伏安法表征
当电极表面有修饰层,电子传递必须通过阻碍层的缺陷进行,因此电活性物质[Fe(CN)6] 3-/4-的循环伏安扫描是表征电子在电极表面传递能力大小的有效方法.图1为裸玻碳电极和壳聚糖修饰玻碳电极在K3Fe(CN)6-K4Fe(CN)6溶液中的循环伏安图.由图1可知,壳聚糖修饰玻碳电极的氧化还原峰电流比裸玻碳电极大,峰电位差ΔEp减小,表明壳聚糖已成功修饰到玻碳电极的表面,在壳聚糖分子链上,分布着许多羟基、氨基等活性基因,分子链上的羟基可与玻碳电极表面的含氧基团作用形成氨基单分子膜.实验结果表明壳聚糖修饰电极提高了玻碳电极的测定灵敏度,促进[Fe(CN)6] 3-/4-在电极表面的反应.同时电位正移也说明Fe(CN)6 3-/4-通过嵌插模式与壳聚糖发生作用[14-16],使小分子物质[Fe(CN)6] 3-/4-在修饰电极膜内发生电子转移,表现出氧化还原峰.

3.2.1 cyclic voltammetry characterization
When the electrode surface have modified layer, electronic transfer must through the block defect layer, so electricity active substances [Fe (CN) 6] 3-/ 4-cycle current-voltage scan is characterized in the electrode surface electronic transmission ability of the size of the effective methods. Figure 1 naked glassy carbon electrode and for chitosan modified glassy carbon electrode in K3Fe (CN) 6-K4Fe (CN) 6 cyclic voltammograms of solution. The figure 1, it is known that chitosan modified glassy carbon electrode REDOX peak current than bare glassy carbon electricity is great, peak Δ Ep reduce the potential difference, show that chitosan has successfully modified glassy carbon electrode to the surface, in the chitosan molecules chain, spread many hydroxyl, amino, gene activity, molecular chain and glassy carbon electrode hydroxyl groups of surface oxygen molecule formation amino membrane. The experimental results show that the modified electrodes chitosan glassy carbon electrode improved determination sensitivity, promote [Fe (CN) 6] 3-/ 4-on the electrode surface reaction. At the same time is also explain Fe potential move (CN) 6 3-/ 4-through the embedded in mode and chitosan occurrence function [14-16], make small molecules [Fe (CN) 6] 3-/ 4-in the modified electrodes membrane happened within the electronic transfer, show REDOX peak.
