    【Abstract】 Objective A novel polarographic catalytic wave method for the determination of ibuprofen was pro-posed.Methods The electrochemical behavior of ibuprofen was studied by liner sweep voltammetry.Results In the supporting electrolyte of0.08mol/L HAc-NaAc(pH=4.2)，ibuprofen produced a catalytic wave at-1.06V.When oxidant K 2 S 2 O 8 was present，a polarographic catalytic wave was produced because K 2 S 2 O 8 oxidized the interme-diate free radical to regenerate the original c=o group.Based on the polarographic catalytic wave ......
