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.}, pages = {321--324}, title = {“Substituent on Benzenesulfonyl Group” Effect in Use of 8-Benzenesulfonamidoquinoline Derivatives as Chelate Extractant}, volume = {19}, year = {2003} }
