Structural Study of Cellulose-Iron Oxide Composite Materials
There are limited structural studies of iron oxide coated cellulose materials despite studies on their use as adsorbents for the removal of waterborne arsenic species.This study reports on the structural characterization of cellulose-iron oxide composites at variable iron oxide content using spectroscopy methods (Raman, solids 13C NMR, powder X-ray diffraction (pXRD)) and thermal gravimetric analysis (TGA).Iron oxide was supported onto cellulose (ca.25 wt.%) without significant loss in the Fe coating efficiency, where the accessibility of the biopolymer-OH groups affect the coating efficiency and yield of the iron oxide-cellulose composite.Isotherm adsorption studies for cellulose, iron oxide species and the cellulose composite materials with roxarsone (3-nitro-4-hydroxyphenylarsonic acid) were studied to characterize the surface chemical properties of the adsorbent materials.
