“…CTS-GLY/KN composite was prepared according to the published method [18]. In this preparation, the CTS-GLY/KN was obtained by combining 1 g CTS flakes and 1 g KN powder (50% CTS: 50% KN, this ratio was predetermined to be the best) in a beaker holding 60 mL of acetic acid solution with 5% v/v concentration while being stirred strenuously for the duration of 24 h at room temperature to dissolve the CTS flakes.…”

“…CTS is featured in the existence of amino (-NH2) and hydroxyl (-OH) groups in its polymeric chain, acting as the prospect adsorption sites for removal of metal ions and anionic dyes [16,17]. However, natural CTS is sensitive to pH changes, mechanically unstable, susceptible to swelling, and leachable in aqueous environment [18]. Hence, it is of great significance to improve the physiochemical properties of CTS.…”

Kaolin clay (KN) was employed as an inorganic filler to modify a cross-linked chitosan-glyoxal as Schiff's-based chitosan composite derivative (CTS-GLY). The resulting (CTS-GLY/KN) was found to be a promising composite synthetic biopolymer that can be potentially utilized for color removal as well as COD reduction of an industrial anionic dye (remazol brilliant blue R, RBBR). The surface porosity, crystallinity, morphology, functionality, charge, and amine content of the CTS-GLY/KN were studied using BET, XRD, SEM, FTIR, pHpzc and pH-potentiometric titration analyses, respectively. Response surface methodology-Box-Behnken design (RSM-BBD) was used to optimize the impact of the main input factors on the color removal and COD reduction of RBBR. The adsorptive performance CTS-GLY/KN towards RBBR was well-defined by both Langmuir and Freundlich isotherm models with highest adsorption capacity of 447.1 mg/g at 30 ˚C. This finding reveals that CTS-GLY/KN can be utilized as a promising, feasible, and environmentally friendly composite-biosorbent for color removal and COD reduction of textile dyes from aqueous medium.

“…Fe 3 O 4 nanoparticles were utilized in a synthesis of various adsorbents due to some advantageous characteristics, such as the presence of surface functional groups, magnetic response ability, small particle size, biocompatibility, and biodegradability [ 32 ]. Thus, the obtaining of a new material based on the insertion of Fe 3 O 4 and Fe 2 O 3 within fly ash represents an interesting research field and a promising pathway to overcome these environmental problems.…”

Fly Ash Coated with Magnetic Materials: Improved Adsorbent for Cu (II) Removal from Wastewater

et al. 2020

Fly ash/magnetite material was used for the adsorption of copper ions from synthetic wastewater. The obtained material was characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) surface area, and vibrating sample magnetometer (VSM). Batch adsorption experiments were employed in order to investigate the effects of adsorbent dose, initial Cu (II) concentration and contact time over adsorption efficiency. The experimental isotherms were modeled using Langmuir (four types of its linearization), Freundlich, Temkin, and Harkins–Jura isotherm models. The fits of the results are estimated according to the Langmuir isotherm, with a maximum adsorption capacity of 17.39 mg/g. The pseudo-second-order model was able to describe kinetic results. The data obtained throughout the study prove that this novel material represents a potential low-cost adsorbent for copper adsorption with improved adsorption capacity and magnetic separation capability compared with raw fly ash.

A magnetic Schiff's base chitosan-glutaraldehyde/Fe3O4 composite (CHT-GLA/ZnO/Fe3O4) was developed by incorporating zinc oxide (ZnO) nanoparticles into its structure to prepare an efficient adsorbent for the removal of remazol brilliant blue R (RBBR) dye. The CHT-GLA/ZnO/Fe3O4 was characterized by the following methods: CHN, BET, FTIR, XRD, SEM-EDX, pHpzc, and potentiometric titrations. Box-Behnken design based on response surface methodology was used to optimize the effects of the A: ZnO nanoparticles loading (0-50%), B: dose (0.02-0.1 g), C: pH (4-10), D: temperature (30-60 °C), and time E: (10-60 min) on the synthesis of the magnetic adsorbent and the RBBR dye adsorption. The experimental data of kinetics followed the pseudo-second order model, while isotherms showed better fit to Freundlich and Temkin models. The maximum adsorption capacity of the target nanocomposite (CHT-GLA/Fe3O4 containing 25% ZnO or CHT-GLA/ZnO/Fe3O4-25) was reached of 176.6 mg/g at 60 °C. The adsorption mechanism of RBBR onto CHT-GLA/ZnO/Fe3O4 nanocomposite can be attributed to multi-interactions including electrostatic attractions, hydrogen bonding, Yoshida Hbonding, and n-π interactions. This study offers a promising hybrid nanobiomaterial adsorbent in environmental nanotechnology to separate and remove the contaminants such as organic dyes from wastewater.
