“Substituent on Benzenesulfonyl Group” Effect in Use of 8-Benzenesulfonamidoquinoline Derivatives as Chelate Extractant Hirayama, Naoki 15804 20260557 Sugisaka, Noriko 15805 Taga, Junko 15806 Oshima, Syunichi 15807 Honjo, Takaharu 15598 90019498 90019498 "Substituent on benzenesulfonyl group" effect of 8-benzenesulfonamidoquinoline [N-(8-quinolyl)benzenesulfonamide, Hbsq] as bidentate chelate extractant for divalent metal cations was investigated with using Hbsq and its eight derivatives. Introduction of electron-withdrawing substituent on the benzenesulfonyl group in Hbsq enhanced the extractability that originated from its inductive effect. Furthermore, a bulky substituent on an ortho-position of the benzenesulfonyl group resulted in no steric effect in extraction, whereas the existence of two substituents on each ortho-position caused lower extraction performance due to steric hindrance. journal article Japan Society for Analytical Chemistry = 日本分析化学会 2003-02-01 VoR application/pdf Analytical Sciences 2 19 321 324 AA10500785 0910-6340 https://kanazawa-u.repo.nii.ac.jp/record/10428/files/SC-PR-HIRAYAMA-N-321.pdf http://hdl.handle.net/2297/29267 https://kanazawa-u.repo.nii.ac.jp/records/10428 eng 10.2116/analsci.19.321 https://japanlinkcenter.org/JST.JSTAGE/analsci/19.321 http://www.jsac.or.jp/ Copyright (c) 2003 by The Japan Society for Analytical Chemistry
