AA and UA on CPB modified electrodes show a irreversible redox process. Both the oxidation peak potentials shift more negatively and the peak currents increase on CPB/CPE,so CPB/CPE can catalyze the electrochemical oxidation of both AA and UA.

• 研究结果表明,在PBS水溶液中,AA和UA在CPB/CPE上氧化峰电流增加,峰电位负移,CPB/CPE对AA,UA电化学氧化反应产生了催化作用。
