A sensitive procedure for determination of micro-traces of Co(II) by adsorptive stripping voltammetry is proposed. The procedure exploits the enhancement of the cobalt peak obtained by use of the system Co(II)-dimethylglyoxime-piperazine-1,4-bis(2-ethanesulfonic acid)-cetyltrimethylammonium bromide. Using the optimized conditions, a detection limit
