Synthesis and characterisation of novel beta-cyclodextrin based Fe ₃ O ₄ nanocomposite: adsorption behaviour and photocatalytic dye degradation studies

International Journal of Environmental & Analytical Chemistry, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 26

Published: July 5, 2024

Novel Beta-Cyclodextrin-based Fe3O4 nanocomposite has been synthesised through copolymerisation by incorporating nanoparticles into the polymer matrix. Ultraviolet-Visible (UV-Visible) spectroscopy, Fourier transform infrared (FTIR) Thermogravimetric (TGA) analysis, Point of Zero Charge, X-ray diffraction (XRD), and Scanning electron microscopy (SEM) analysis have used to characterise Nanoparticles β-CDHs@Fe3O4 nanocomposite. The utilised for adsorption methylene blue (MB) dye from aqueous solutions. maximum percentage removal MB at optimum pH 7 was found be 98.51%. capacity (qe) 268.09 mg/g dosages 1.2 g/L, 7, temperature 25°C, concentration 100 mg/L an agitation speed 200 rpm. Adsorption data fitted with three isotherm models namely Langmuir, Freundlich, Temkin, it best fit Langmuir model. Kinetic studies like pseudo-first order, pseudo-second intra-particle diffusion model were also performed study mechanism. Further, thermodynamic demonstrate that reaction exothermic spontaneous. Photocatalytic degradation under visible light studied, 79.01% observed. Also, desorption performed, reusable up 5 times 90% dye-desorption in fifth cycle.

Water pollution represents one of the most important problems affecting health living organisms, so it was necessary to work on formation active materials get rid pollutants. In this study, Titanium dioxide (TiO2) doping Zinc oxide (ZnO) nanocomposites were produced via simple sonication method at 500 Hz in ethanol medium. different weight concentrations (2.5, 5, 7.5, and 10%). The morphology, structure configuration, chemical bonding, crystalline phase, surface properties obtained characterized FESEM, BET, XRD, XPS, RAMAN FTIR instrumentation. employed as an adsorbent eliminate methyl orange (MO) Indigo Carmine (IC) dyes from aqueous solution. Batch removal experiments revealed that elimination MO IC by TiZnO pH Ti concentration-dependent, with maximum occurring = 7 for 3 contaminants 10% concentration (Ti(10%)@ZnO). Langmuir model fit absorptive into Ti(10%)@ZnO well. maximal capacity nanocomposite found be 994.24 mg. g-1 305.39 IC. showed remarkable high stability towards both through consecutive four cycles.
