摘要
Abstract
The color reaction between dicyclohexanoneoxalyldihydrazone (BCO) and copper ( II ) had been studied, and determination method of trace copper in aluminum alloy by spectrophotometry was established. In the presence of surfactant CTMAB and in the NH3. H20-NH4C1 buffer medium, copper( Ⅱ ) and BCO forms a blue complex, the complex has a maximum absorption at 606 nm. Beers's law is obeyed in the range of 0-80 μg in the solution of 25 mL for copper( 11 ). The apparent molar absorptivity is 1.79104 L?mol-1?cm-1. The method was rapid and simple to determinate copper in aluminum alloy with satisfactory results.关键词
