Preconcentration and separation of cadmium by use of cobalt(III) hexamethylenedithiocarbamate as a collector prior to its determination by atomic absorption spectrometry

Co(III) hexamethylenedithiocarbamate has been applied as a collector in col loid notation preconcentration of ed from water prior to electrothermal ato mic absorption spectrometry (ETAAS). AU experimental parameters necessary f or successful flotation have been studied and optimized. The ETASS results were compared with these obtained by inductive coupled plasma-atomic emissi on spectrometry (ICP-AES). The ETAAS detection limit was found to be 0.003 mug L-1 Cd.
