Using PEDOT Film Modified Electrode to Monitor Iodide and Its Enhancement of Arsenite Sensing
Iodide was investigated using poly(3,4-ethylenedioxythiophene)/glassy carbon electrode (PEDOT/GCE) as an monitoring tool. When this electrode was scanned to the positive potential (+0.7 V) in the presence of 6×10(-3) M, the redox couple was gradually separated into two redox couples involving the iodide/triiodide and triiodide/iodine redox processes due to the iodide doping behavior occurs easily with the sufficient positive potential and the higher iodide concentration. The I-2-PEDOT may be the doping result and it lowers the activation energy of iodide redox processes. The PEDOT/GCE shows linear current response (I-pa(mA) = 21.553[KI](M) + 8.2602, R-2 = 0.9995, S/N = 3) to iodide. Through the iodide mediator, PEDOT/GCE can determine As(III) with a sensitivity of 303.3 mu A mM(-1) cm(-2). Particularly, it can enhance the current response for As(III) by increasing the iodide molar ratio. The current ratio of IAs(III)/II-was about 1.66 amplification when molar ratio of n(I)-/n(As)(III) was 0.3.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 507-63-1. Recommanded Product: Heptadecafluoro-1-iodooctane.
