Comparative <sup>13</sup>C NMR Spectroscopy of Lignocellulose Sorbents
Abstract
The composition and structure of initial and modified lignocellulose materials have been investigated by 13C NMR spectroscopy. Changes in functional structure and composition of the samples have been found to arise due to modifying as a result of chemical transformations and hemicelluloses removing. Sorption properties of lignocellulose composites have been studied in relation to heavy metals. They have been found to depend on changes in the composition and functional structure of the materials.References
