以金电极和HB铅笔芯电极为工作电极,选取Ru(bpy)32+-盐酸苯海索体系为考察对象,通过电化学、化学发光,研究不同工作电极对Ru(bpy)32+-盐酸苯海索体系电致化学发光行为的影响。结果表明,在p H=7.5硼酸盐缓冲溶液和扫描速率0.10 V·s-1条件下,在一定盐酸苯海索浓度范围内与电致化学发光强度值呈良好线性关系,其中金电极测定时浓度范围为1.00×10-8mol·L-1~2.00×10-5mol·L-1(R2=0.9938),HB铅笔芯电极测定时浓度范围为1.00×10-8mol·L-1~1.00×10-4mol·L-1(R2=0.9874),且两者重现性均较好。
Using Ru (bpy) 32 + -Hydroxybenzene system as the working electrode, the gold electrode and HB pencil core electrode were selected as the working electrode. Electrochemical and chemiluminescence methods were used to study the effect of Ru (bpy) 32 + Effect of Hydroxybenzene on Electrochemiluminescence Behavior. The results showed that there was a good linear relationship between the electrochemiluminescence intensity and the electrochemiluminescence intensity at a certain concentration of trihexyphenidyl HCl in p H = 7.5 borate buffer solution and a scanning rate of 0.10 V · s-1. Concentration of 1.00 × 10-8mol·L-1 ~ 2.00 × 10-5mol·L-1 (R2 = 0.9938). The concentration range of HB pencil electrode was 1.00 × 10-8mol·L-1 ~ 1.00 × 10-4mol·L-1 (R2 = 0.9874), and the reproducibility of the two were better.
