Abstract:
Discharge of industrial effluents containing dyes is one of the main causes of water pollution, hence there is need of proper treatment and handling of these contaminated effluents before their release. Therefore, an eco-friendly and biodegradable magnetite nanoparticles-linked gum acacia composite was synthesized via an in-situ polymerization approach to evaluate their potential use as an adsorbent for the uptake of organic contaminants from wastewater. The composite was structurally characterized by advanced instrumental techniques such as FT-IR, XRD, SEM, EDX, VSM, and TGA. The results displayed the magnetic, high crystalline, and porous Fe3O4@GA composite fabrication. The saturation magnetization value was found to be 23.1 emu/g. The composite was found to be an efficient adsorbent for Congo red (96.1% adsorption) and Crystal violet (95.4% adsorption) dyes, under optimized conditions of concentration, pH, amount of adsorbent, contact time, and temperature. A pseudo-second-order kinetic model has been suggested for the composite with an R2 value equal to 0.99 and the Langmuir adsorption isotherm model exhibited R2 = 0.9995. The thermodynamic studies demonstrated the adsorption experiments' feasibility, exothermic nature, and spontaneity. The composite showed higher desorption (95%) and reproducibility, retaining the same % removal efficiency of dyes repeatedly up to three cycles, indicating a dynamic composite for its potential application in water treatment.
