Cellulose beads possess some adsorption capacities for heavy metal ions, but the effect of lignin remaining in the beads on the adsorption behavior is not clear yet. In this study, lignocellulosic and cellulosic hydrogel beads were prepared by ionic liquid (IL) dissolution and reconstitution in water and further functionalization through magnetization and carboxymethylation. Compared to pure cellulosic...
Suitable α-cellulose and cellulose II powders for use in the pharmaceutical industry can be derived from maize cob. α-Cellulose was extracted from an agricultural residue (maize cobs) using a non-dissolving method based on inorganic substances. Modification of this α-cellulose was carried out by its dissolution in the ionic liquid 1-butyl-3-methylimidazolium chloride ([C4mim]Cl), and subsequent regeneration...
