چکیده:

in this study a new method of dispersive liquid phase micro extraction DLPMEwas proposed for the determination of trace Co using 1-2-pyridylazo 2-naphthol PAN as chelating reagent. The procedure is based on a ternary system of solvent where appropriate amounts of the extraction solvent disperser solvent and the chelating agent PAN are directly injected into and aqueous solution containing cobalt.
