Copper can be determined spectrophotometrically at 600 nm based on the reaction of copper(H) and bis(cyclohexanone)oxalyldihydrazone using flow-injection analysis. The carrier stream was distilled water and the reagent streams were 27% (w/v) citric acid solution, 37% (v/v> ammonia solution and 0.18%
