Abstract
Two coflotation methods for separation of silver in traces from water matri ces using iron(Ill) hexamethylenedithiocarbamate, Fe(HMDTC)(3), and cobalt( Ill) hexamethylenedithiocarbamate, Co(HMDTC)(3), as collectors were propose d. After coflotation silver was determined by electrothermal atomic absorpt ion spectrometry (ETAAS). The optimal conditions for effective silver coflo tation performed separately by each collector were established. The results of ETAAS analyses are compared with those obtained by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The limit of detection of ET AAS using both Fe(HMDTC)(3) and Co(HMDTC)(2) as collectors is 0.003 mug/L A g.
