Abstract
Anodically Polymerized conducting Polypyrrole film electrode was employed to Pick up uranyl ion with the type of Gr/ppy, xylenol orange modified electrode. To have Porous and oriented ppy film, NBR was applied as precoating agent. The rate constant of polymerization was which was 1.6 times smaller value than bare graphite surface. The deposited amount of uranyl iou on of ppy was . The matrix effect in artificial seawater was . The polymer film electrode has a diffusion controlled process in conduction, but the modified Gr/ppy, type was influenced on the ion doping and electronic conduction of film itself owing to increasing of impedance. The capacitance of electrical double layer was respectively enhanced to 56 and 130 times in Gr/ppy, and Gr/ppy, than Grippy type electrode.
