Abstract: Based on the electrochemical micro probe and the weak signal detection technique, simulated test and measurement system were set up by the use of four_electrode cell(including a micro electrode), bipotentiostat, lock_in amplifier and three_dimensional micro manipulating device. Based on the system, the micrometer scale concentration distribution of trace hypochlorite, which is produced by direct electrolysis of seawater on the conducting film for preventing microbial corrosion has been obtained for the first time. Both relationships between concentration of hypochlorite and its reduction current, which is termed an working curve, and between the reduction current of hypochlorite and measured time are reported.

Key words: Direct electrolysis of seawater, Conducting film, Microbial anticorrosion, Concentration of sodium hypochlorite
