Herein, Ag/TiO2 nanocomposite was synthesized via a green chemistry approach, which is an eco-friendly, simple, and cost-effective method involving mangosteen pericarp extract as reducing agent. The as-prepared nanocomposites were characterized using X-ray powder diffraction (XRD), Fourier transformation infrared spectroscopy (FT-IR), UV-Vis spectrophotometer, Scanning electron microscopy (SEM), Energy dispersive (EDS), Transmission (TEM), Zeta potential measurement, nitrogen (N2) adsorption-desorption analysis. performance of examined by degradation methylene blue (MB) dye model organic pollutant. the containing 45 mM Ag revealed high MB degradation, 85.77 % after 30 minutes under dark condition. Furthermore, complete 96.76 achieved 2 hours visible light irradiation. In contrast, bare TiO2 only 41.45 This increase in efficiency can be attributed to adsorption process enhanced absorption resulting from localized surface plasmon resonance (LSPR) effect Ag. Therefore, green-synthesized has great integrated adsorbent photocatalyst materials for remediating pollutants effluents.

The Potential of Bentonite as a Low-cost Adsorbent for the Removal of Heavy Metal Ions from Multicomponent Aqueous Systems of the Galvanic Industry

International Research Journal of Pure and Applied Chemistry, Год журнала: 2024, Номер 25(2), С. 28 - 39

Waste water in the galvanic process contains high concentrations of heavy metals that pose a direct danger to humans and environment. Conventional methods for their removal are quite expensive generate large amount waste. The development new improvement existing from wastewater subject many studies. Compared other purification methods, adsorption is becoming an increasingly popular method purification, especially if adsorbent cheap, easily available does not require any treatment before use. Therefore, aim work was investigate possibility using natural bentonite metal ions multi-component systems industry. For this purpose, physico-chemical characterization performed, then influence pH value, time temperature on efficiency examined. results showed can be used as waste waters, at 5 it achieves maximum Cu(II):Cr(III):Ni(II) percentage ratio 100 : 99.990 99.998. highest Cu (II) achieved first 10 minutes, 20 minutes Cr (III) Ni ions. all temperatures, while 99.99% 100% 35°C, which indicates endothermic. experimental good agreement with Langmuir Freundlich theoretical models, they better model.
