A sensitive stripping voltammetric determination of Co (II) is described, based on the
selective accumulation of its complex with ammonium 2-aminocyclohexene-1-
dithiocarbamate on HMDE and subsequent reduction of the complex in the presence of
nitrite as a catalyst. The peak potential is about-1.35 V vs. Ag/AgCl reference electrode at
pH= 10.0. The calibration graph was linear for the range of 0.01-40 ng/ml, with a limit of
detection of 8.0 pg/ml. The relative standard deviation for ten replicate analyses of 1.0 ng/ ...
