The electroanalytical detection and determination of copper in heavily passivating media: ultrasonically enhanced solvent extraction by N-benzoyl-N-phenyl-hydroxylamine in ethyl acetate coupled with electrochemical detection by sono-square wave stripping voltammetry analysis.
N-benzoyl-N-phenyl-hydroxylamine dissolved in ethyl acetate was employed as a ligand for the solvent extraction of copper. Ultrasonic emulsification was shown to be effective both in the extraction of copper from an aqueous phase into ethyl acetate and its recovery or "back extraction" int...
