Characterization of cross-linked cellulosic ion-exchange adsorbents: 1. Structural properties.

Highlights: [•] We examine the structural characteristics of cellulosic ion-exchange adsorbents. [•] Inverse size exclusion was used to estimate the pore size distribution. [•] Pore space in HyperCel is comparable to that in a polymer-modified adsorbent. [•] Electron microscopy imaging was used to qualitatively assess the pore structure. [•] Functional characterization of the Donnan equilibrium showed salt exclusion. [Copyright &y& Elsevier]
