“…Commercially available activated carbons are usually derived from natural materials such as wood, coconut shell, lignite or coal, but almost any carbonaceous material may be used as precursor for the preparation of carbon adsorbents [91]. Because of its availability and cheapness, coal is the most commonly used precursor for activated carbon production [92].…”

“…Effluents discharged from dyeing industries are highly colored with low biochemical oxygen demand (BOD) and high chemical oxygen demand (COD). 23 Disposal of these effluents into water can be toxic to aquatic life. 24 The dyes upset the biological activities in water bodies.…”

“…They cause a health problem because they may be mutagenic and carcinogenic 25 and can cause severe damage to human beings such as in the liver and the central nervous system. 23,26 Different techniques, such as membrane separation, flocculation, chemical oxidation, and adsorption, are investigated to treat reactive dyes wastewater. Among them adsorption technology is generally considered to be an effective method for quickly lowering the concentration of dissolved dyes in an effluent.…”

The graft copolymerization of acrylic acid (AA) onto starch was carried out with monomer/starch weight ratio 5 1.5. Cerium ammonium nitrate (CAN) and N,N 0 -methylenebis acrylamide (NMBA) were used as initiator and crosslink agent, respectively. Na-montmorillonite was used as nanoparticles. Starch-graft-acrylic acid/Na-MMT (S-g-AA/MMT) nanocomposite hydrogels were characterized by X-ray diffraction (XRD) and FTIR analysis. The effect of Na-MMT content in nanocomposite hydrogels on the swelling behavior was investigated. Increasing the Na-MMT/monomers ratio up to 1% causes an increment in water absorbency, which indicates that Na-MMT can improve the ability of water absorbency but further increase of Na-MMT causes a decrease in water absorbency. In addition, we describe the removal of safranine T from aqueous solutions using S-g-AA/MMT nanocomposite hydrogels. Effects of various parameters such as treatment time, initial dye concentration, and amount of the Na-MMT were investigated. The Freundlich equations were used to fit the equilibrium isotherms.

“…Dyes can be effectively removed by adsorption process. Activated carbon [10], natural clays [11,12], modified clays [13][14][15], some industrial wastes and by-products, agricultural residues [16,17] have been used as adsorbents for removal of organic compounds from wastewater. In recent years, polymeric adsorbents have been increasingly used to remove and recover organic pollutants from wastewaters [5,[16][17][18][19][20][21][22].…”

In this study, graft copolymerization of itaconic acid (IA) and crotonic acid (CA) onto the crosslinked chitosan beads were carried out using ammonium persulfate as initiator. Grafted chitosan beads were characterized by FT-IR analysis and grafting percentage determination. Grafting efficiency and add-on percentages values of grafted chitosan beads were determined as 23-29 and 32-47%, respectively. Then, equilibrium isotherms and kinetics of brilliant green adsorption onto grafted chitosan beads were investigated. The results indicated that the pseudo-second-order kinetic model fitted better than the data obtained from pseudo-first-order model for the adsorption of brilliant green onto grafted chitosan beads. The fit of data for brilliant green (BG) adsorption onto grafted chitosan beads suggested that the Langmuir model gave closer fittings than the Freundlich model.
