Abstract
|
|
|
|
A spectrophotometric method for the determination of copper using N,N'-Oxalylbis(salicylaldehyde hydrazone) as a chromogenic reagent has been developed. Determination has been performed by measuring the absorbances of the copper complexes in solutions containing 60% dimethylformamide (pH 2) at 422 nm. The method allows the determination of 0.4∼1.8 μg/ml of copper and has been applied to its determination in synthetic mixtures and alloy samples.
