著者：Hiroki KODAMA, Tohru MIYAJIMA, Kotaro NAKATA題名：Characterization of tetramethylammonium ion binding to fulvic acid molecules by the use of 1H DOSY method.発表情報：17th IHSS conference (in greece)キーワード：DOSY, tetraalkylammonium, fulvic acid, cationic probe, polyelectrolyte, hydrophobicity概要：抄録：Abstract
Binding of cationic organic molecule, tetramethylammonium ions(TMA+) to dissociated fulvic acid molecules(FA-) of various origins has benn evaluated by using 1H DOSY method. Chemical shift() together with diffusion coefficient (D) value have been determined as a function of , the degree of neutralization of FA molecules. Specific interaction between TMA+ and moieties of FA- molecules has been revealed, which is dependent of the chemical nature of the FA- samples examined. The results were compared with a PAA-/TMA+ system, where TMA+ ions bind to PAA- mainly due to territorial binding mode. 1H DOSY method can characterize the counterion binding to FA molecules.英語フィールド
