The utilization of nanocomposite hydrogels in wastewater treatment has become one of the most important and remarkable issues in recent years. In this research project regarding to the importance of nanomaterials and bio-polymers, we tried to design and construct a new organic-inorganic hybrid nanomaterials with enhanced dye removal efficiency containing cellulose nanowhiskers and Mg/Al-CO layered double hydroxide (LDH) as organic and inorganic nanoscale materials, respectively. For this purpose, cellulose nanoparticles fabricated and modified through free radical graft polymerization of acrylic acid in presence of as prepared Mg/Al-CO-LDH. The successful preparation of the product was evaluated using FT-IR, UV-vis, TGA, SEM, BET and XRD techniques. Also, the applicability of the prepared nanocomposite hydrogel (cellulose nanowhisker-graft-PAA/LDH) for removal of several cationic dyes was investigated. Kinetics study showed that adsorption onto the nanocomposite hydrogel was fitted into second order model for all of the dyes. The maximum adsorption capacity of nanocomposite hydrogel for cationic dyes were in range of 21-27 mg g that showed significant improvement in comparison with the cellulose nanowhisker-graft-PAA hydrogel. For example, the percentage of dye removal increased from 33% by hydrogel to about 96% by nanocomposite hydrogel for Fuchsine. Furthermore, the hydrogel applied several times and showed stable performance after three adsorption-description cycles.

Inorganic derivatives of ammonia by substitution of one or more hydrogen atoms with chlorine atoms or organic compounds with the general formulas R2NCl and RNCl2 (where R is an organic group).
Compounds derived from organic or inorganic acids in which at least one hydroxyl group is replaced by an –O-alkyl or other organic group. They can be represented by the structure formula RCOOR’ and are usually formed by the reaction between an acid and an alcohol with elimination of water.
Screening techniques first developed in yeast to identify genes encoding interacting proteins. Variations are used to evaluate interplay between proteins and other molecules. Two-hybrid techniques refer to analysis for protein-protein interactions, one-hybrid for DNA-protein interactions, three-hybrid interactions for RNA-protein interactions or ligand-based interactions. Reverse n-hybrid techniques refer to analysis for mutations or other small molecules that dissociate known interactions.
