摘要：

A new-type of polarographic catalytic wave of organic compound,the polarographic catalytic wave of cinnamic acid (CA) in the presence of tetra-butylammonium bromide (Bu4NBr) and H2O2, is reported based on the combination of the reduction current of adsorbed CA induced by Bu4NBr with the catalytic current of CA caused by H2O2. The dual enhancement of both Bu4NBr and the oxidizing agent H2O2 on the polarographic current of CA produces excellent sensitivity.
