Abstract
A new reagent 3,3′-(1,3-propanedyldiimine)bis-[3-methyl-2-butanone]dioxime (PnAO) has been prepared and used for developing a simple spectrophotometric method for the determination of copper which is based on a 1 : 1 complex formation between copper(II) and PnAO in aqueous solution. The method is optimized in terms of pH, stability of the complex, amount of reagent required, sensitivity, linearity and tolerance limits of various foreign ions. The new photometric method was also applied for the determination of copper in environmental samples.
