The removal of copper from diluted aqueous solutions with ACORGA M5640 extractant using non-dispersive solvent extraction technology was studied. It was possible to remove Cu(II) below the international standars from solutions having initially as low concentration as 0,01 g/l under various experimental conditions, i.e aqueous pH 4.0, 10 % v/v ACORGA M5640 in Exxol D100, an organic flow of 100 ml/min, and an aqueous flow 50ml/min. Since the removal occurs by chelating ion exchange between copper from solution and protons from the extractant, the former was stripped by using a 180 g/l sulphuric acid solution which flowed (50 ml/min) through the tube side organic was passed (400 ml/min) through the shell side of the fibers of the module
