4‐Chloro‐ N ‐8‐quinolinylbenzenesulfonamide (HL) was synthesised and characterised by elemental analysis, IR and FT‐Raman spectroscopy. The synthesised reagent dissolved in toluene was used for copper(II) extraction from 1.0 mol dm −3 KNO 3 . The experimental extraction data have been treated graphically and numerically and the complexes CuL 2 and Cu(NO 3 )L have been proposed as being responsible for the metal extraction. Values of the corresponding stoichiometric extraction constants have been determined. Copyright © 2004 Society of Chemical Industry
