A method of recovering copper(II) from acidic solutions, especially from waste and digestive solutions POLISH PATENT NO. P.240363 (2022)
Description: The present invention relates to a method of recovering copper(II) ions from acidic solutions, in particular from waste and digestive solutions. The essence of the invention is the method of solvent extraction of copper(II) ions using 2,6-bis(4- methoxybenzoyl)-diaminopyridine as the extractant. This innovation enables the removal of about 99% of the copper(II) ions from the acidic solutions using a 0.001 M solution of the tested extractant in chloroform.
