Abstract:In 0.12nik.L-1 KCl solution,a well reduction peak of cimetidine is obtained by single-sweep oscillopolarography.The peak potential is-1.09V(vs.SCE).The peak cur-.rent is proportional to the concentration of cimetidine over the range of 1.0 10-6~1.510-5molL-1.The detection limit is5.010-7mol.L-1.The method is applied to the determinationof cimetidine in tablet with satisfactory results.The voltammetric and adsorptive behavior ofthe system is studied by means of linear sweep and cyclic voltammetry.The wave is a quasi-reversible wave with adsorptive property.
Keywords:cimetidine  voltammetric behavior  adsorptive behavior  single-sweep oscillo-polarography
