| Abstract: |
In the present study, grafting of acrylic acid and itaconic acid copolymer onto carboxymethyl cellulose backbone was performed by a free radical polymerization approach to decontamination of crystal violet and malachite green from aqueous media. To promote removal efficiency, various amounts of Cloisite 30B nanoclay were integrated into the hydrogel matrix, and the optimum value based on the removal performance was obtained 6 wt.%. The optimum pH values, initial concentration, and contact time were determined to be 7, 30 mg/L, and 140 min. The kinetic and equilibrium data were well defined by quasi-second-order and Langmuir models. The maximum adsorption capacity of hydrogel and nanocomposite hydrogel from the Langmuir model was obtained at 45.87 and 58.48 mg/g for crystal violet and 25.51 and 36.36 mg/g for malachite green, respectively. The FTIR analysis before and after dye adsorption showed that electrostatic interaction is the main mechanism of the adsorption process. It can be concluded that synthesized adsorbents have high potential in wastewater treatment applications. [ABSTRACT FROM AUTHOR] |
