Extraction and spectrophotometric determination of copper(II) with 1,1,1-trifluoro-3-(2-thenoyl)acetone.
Copper(II)-trifluorothenoylacetone complex in chloroform does not undergo decomposition when scrubbed with sodium hydroxide solution. This allows the complete removal of the residual reagent, and a highly sensitive method for the extraction and spectrophotometric determination of copper(II) results.
