Abstract
In this paper, a chitosan modified glassy carbon electrode was prepared by the method of covalent-bond reaction, and the anodic stripping voltammetric characteristics of iodine on the modified electrode was studied. The results showed that the modified electrode has higher adsorption and selectivity for I~-, and the sensitivity for I~- has been much improved in 0.1 mol·L~(-1) KH_2PO_4 solution (pH=4.0). The anodic stripping peak current of I~- on the modified electrode varied linearly with I~- concentration in the range of 2.0×10~(-6)～2.0×10~(-3) mol·L~(-1), and the detection limit reached 2.0×10~(-7) mol·L~(-1).
