Abstract: Codeposition and costripping models for bimetal from Ag+, Cu2+, Pb2+, Sn2+, and Cd2+, on boron-doped diammond (BDD) surface were studied with differential pulse anodic stripping voltammetry. The results showed that bimetal codeposition and costripping models on BDD surface were determined by deposition potential of metals, mutual inferences between two kinds of metals, interactions of metal and electrolytic solution and so on. In addition, four types of codeposition and costripping models for bimetal were summarized: (1) metal 1 stripping-metal 2 stripping; (2) metal 1 stripping-hydrogen evolution-metal 2 stripping; (3) metal 1 stripping-alloy striping-metal 2 stripping; (4) metal 1 stripping-hydrogen evolution-complex forming-metal 2 stripping.

Key words: Bimetal, Boron-doped diamond surface, Codeposition and costripping model, Differential pulse anodic stripping voltammetry
