A novel separation/preconcentration technique based on ultrasonic dispersion liquid-liquid microextraction for determination of trace cobalt by flame atomic absorption spectrometry
2012
Bulletin of the Chemical Society of Ethiopia
An improved method for the determination of trace cobalt in water samples has been developed using ultrasonic dispersion liquid-liquid microextraction (US-DLLME) prior to flame atomic absorption spectrometry (FAAS) analysis. In this method, cobalt was extracted into the fine droplets of carbon tetrachloride after chelate formation with the water soluble ligand, ammonium pyrrolidine dithiocarbamate (APDC). The fine droplets of carbon tetrachloride were formed and dispersed in the aqueous sample
