Some Interactions of Water-Soluble Solutes with Cellulose and Sephadex

Abstract
Elution of a variety of types of water-soluble solutes from gel-permeation columns of chopped native cotton and of Sephadex G-15 was studied. Evidence was obtained concerning (a) the fraction of internal water that is available as solvent water for selected types of solutes, (b) the sorption of strong donor and acceptor hydrogen-bonding solutes on cellulose and Sephadex surfaces, and (c) negative sorption (or repulsion) of carboxyl-containing solutes.
