摘要：

A simple, direct, highly sensitive and selective spectrophotometric method has been developed for the determination of copper(II). It is based on the reaction at pH 9.2 between nicotinohydroxamic acid and Cu(II) forming a stable green coloured complex. It exhibits a constant and maximum absorption at 800 nm. The system obeys Beer's law over a wide range of concentration. The proposed method can be applied for the determination of Cu(II) without interference from a variety of ions. The proposed procedure has been successfully applied to the analysis of Cu(II) in natural samples, industrial effluents and alloys.
