In this work, chitosan, a biopolymer was cross-linked using glutaraldehyde (Gl) and modified by natural apatite. The Cs-Gl@Fap composite used to adsorb methyl orange from an aqueous solution. materials were characterised SEM-EDX, FTIR, XRD TGA-DTG analysis confirming the successful synthesis of Cs-Gl@Fap. effects experimental variables on adsorption efficiency examined. Adsorption studies showed that maximum capacity 225.55 mg/g at equilibration time 120 min. pseudo-second-order rate...
A rapid gelation method was used to fabricate magnetic chitosan/graphite/polyvinyl alcohol (m-CGPA) hydrogel beads crosslinked with glutaraldehyde. thorough characterization carried out by FTIR, SEM-EDX, XRD, VSM, and TGA. Studies batch experiments indicated that m-CGPA removes more than 95% of reactive orange 16 (RO 16) dye a Langmuir monolayer adsorption capacity 196.3 mg/g at pH 4.0 in just 90 min contact time. isotherm model fitted well the experimental data. Pseudo-second order kinetics...
Polymers have been proven to be an interesting class of adsorbents applied in water treatment. Biopolymers are special interest due their unique properties such as biocompatibility, biodegradability, and reusability. This work reports a composite formed by chitosan biopolymer activated charcoal using sodium citrate crosslinking agent. The chitosan–citrate-activated (CCA) was characterized FT–IR, SEM, EDAX, XRD, TGA–DTA BET surface area analysis. material found microporous nature with 165.83...
A cellulose biopolymer was doped with Fe and Al forming a mesoporous composite. The composite showed excellent adsorption capacities of 117.86 mg g −1 95.62 for Reactive red 21 blue 19 respectively.
This work synthesized a novel chitosan-loaded MgAl-LDH (LDH = layered double hyroxide) nanocomposite, which was physicochemically characterized, and its performance in As(V) removal antimicrobial activity evaluated. Chitosan-loaded nanocomposite (CsC@MgAl-LDH) prepared using cross-linked natural chitosan from shrimp waste modified by Mg–Al. The main mechanisms predominating the separation of were elucidated. characteristic changes confirming modification with analyzed through Fourier...
Cellulose-Sn(IV) (CSn) biocomposite was synthesized by cellulose and stannic chloride in ethanol medium using microwave irradiation for 2 min with 30 s of intermittent time intervals. The incorporation Sn(IV) into the matrix confirmed through FT-IR, XRD, TGA, SEM- EDS, BET. prepared composite CSn has been used adsorptive removal As(III) from water. Parameters, such as initial concentration, adsorbent dose, required adsorption process, were optimized batch-adsorption process. capacity found...
A composite of chitosan with Mohr's salt was prepared by microwave irradiation method. This novel chitosan-ferrous ammonium sulphate characterized using various techniques like FT-IR, SEM, EDX, TGA-DTA, XRD and pHpzc. The material used for adsorptive removal Indigo Carmine dye from aqueous solution batch experiments as well Response Surface Methodology. screening in accordance Plackett-Burman design followed Central Composite Design led to optimization operating parameters. When the...
Aluminium industry waste red mud was combined with Chitosan so as to prepare novel composite in the form of beads. The Red mud–Chitosan beads (Rm-Ch) were studied for applicability removal fluoride, chromate and phosphate ions from aqueous solution. characterized surface morphology, elemental analysis, thermal stability presence functional groups. Thermodynamic, kinetics isotherm studies carried all three anions revealed that adsorption process is spontaneous, exothermic follows pseudo...
