title: Cation/macromolecule interaction in alkaline cellulose solution characterized with pulsed field-gradient spin-echo NMR spectroscopy.
abstract: As a breakthrough to the traditional1H diffusometry, the interaction of cations with cellulose is investigated via7Li and23Na PFG-SE NMR. The diffusion coefficient of Li+decreases more than that of Na+with the addition of cellulose, which indicates a stronger binding of LiOH with the macromolecule. Therefore, a new, facile, accurate and repeatable method to characterize ion/polymer interactions is established.
