The optimum accumulation potential and accumulation time were +0.15 V and up to 180 s, respectively. Linear calibration graphs were obtained between 3.9 mu g.L-1 to 39 mu g.L-1 and the limit of determination was evaluated to be 1.9 mu g.L-1. The method was applied successfully to the determination of cefaclor in pharmaceutical formulations.97-109engcefaclorpharmaceuticalsstripping voltammetryhanging mercury dropArtigo10.1080/00032719908542601WOS:000078552100008Acesso restrito0000-0002-2296-1393
