In 0.1mol/L H_2SO_4 sporting electrolyte, a reduction poak of anferpramon(ANF) was found by linear-sweep voltammetry at Hg electrode.The peak shows a potential of -0.76V(vs.Ag/AgCl) and adsorptive characteristics. The saturated adsorption amount of ANF is 2. 6×10￣(-10)mol/cm￣2. The transfer coefficient a of the irreversible adsorptive system of ANF is 0. 63.I_(pc) is direcily proportional to the concentration of ANF over the range from 2. 0× 10￣(-9)-6.0×10￣(-7)mol/L,with a detection limit of 1.0×10￣(-9)mol/L. The electrochemical behavior of the system and its reaction mechanism were studied too.
