pH Controlled Condition for Selective Simultaneous Determination of Nickel and Cobalt in Alloys by First Derivative Spectrophotometry
1-(2-Pyridylazo)-2-naphthol (PAN) has been used for the simultaneous determination of nickel and cobalt at trace levels. PAN complexes of nickel and cobalt in the pH 1.89 form red and green colored complexes, respectively which are soluble in aqueous Tween 80 micellar media. Under optimum conditions...
