Abstract
A novel kinetic spectrophotometry for determination of trace copper is established based on the redox reaction between O 2 and gallocyanine catalysed by copper in weak acid medium.The calibration graph is linear between 0.05~0.5 μg/mL Cu 2+ ,and the detection limit is 0.02 μg/mL .Copper content in such samples as solid and water is determined,and the results are satisfactory.
