Sulfonamide-Type Monoanionic Bidentate Ligands as Possible Chelate Extractants for theCopper(II) Cation Kato, Chikako 16179 Sugisaka, Noriko 16180 Hirasawa, Eri 16181 Oshima, Shunichi 16182 Hirayama, Naoki 15804 20260557 To evaluate the possible use of sulfonamide-type monoanionic N,N --bidentate ligands as chelate extradants for divalent metal cations, we studied the chelate extraction behavior of copper(II) cation into chloroform with several N-C2-N- bidentate ligands having the p-toluenesulfonamido group as a model system. All of the four N-C 2-N- ligands studied showed quantitative extractability for copper(II) and the metal:ligand ratio in the extracted species was 1:2. Furthermore, the order of the extraction constants for copper(II) with the ligands suggests that the number of π-electrons in the N-C2-N - structure is an important factor in achieving high complexation ability and extractability. journal article Japan Association of Solvent Extraction = 日本溶媒抽出学会 2007-01-01 VoR application/pdf Solvent Extraction Research and Development, Japan 14 171 176 AA11114608 1341-7215 https://kanazawa-u.repo.nii.ac.jp/record/10617/files/SC-PR-KATO-C-171-176.pdf http://hdl.handle.net/2297/35243 https://kanazawa-u.repo.nii.ac.jp/records/10617 eng
