Abstract : A simple adsorptive cathodic stripping voltammetry method has been developed for antimony (III and V) speciation using 4-(2-thiazolylazo) - resorcinol (TAR). The methodology involves controlled preconcentration at pH5, during which antimony(III) - TAR complex is adsorbed onto a hanging mercury drop electrode followed by measuring the cathodic peak current (Ip,c) at -0.39V versus Ag/AgCl electrode. The plot of Ip,c versus antimony(III) concentration was linear in the range 1.35×10-9-9.53×10-8mol L-1.The LOD and LOQ for Sb(III) were found 4.06×10-10 and 1.35×10-9mol L-1, respectively. Antimony(V) species after reduction to antimony(III) with Na2SO3 were also determined. Analysis of antimony in environment water samples was applied satisfactorily.
