【Abstract】 The preparation and el ec trochemical behavior with the gelatin film containing K 8[CeW 10O 36 ].30H 2O(denoted as CeW 10)are described in detail. This modified ele ctrode has a high stability and redox activity in aqueous acidic medium. It is c onfirmed that CeW 10 can be stably adhered on the surface of GC electrode. The pH of the supporting solution greatly influences the electrochemical behavio r of CeW 10. The experimental results show that the GC electrode modified w ith the gelatin film with CeW 10 has produced a strong catalytic effect on the reduction of chlorate and bromate anions in the solution.更多还原
