Graphene for separation and preconcentration of trace amounts of cobalt in water samples prior to flame atomic absorption spectrometry
A new sensitive and simple method was developed for the preconcentration of trace amounts of cobalt (Co) using 1-(2-pyridylazo)-2-naphthol (PAN) as chelating reagent prior to its determination by flame atomic absorption spectrometry. The proposed method is based on the utilization of a column packed...
