Purification of Biodiesel Polluted by Copper Using an Activated Carbon Prepared from Spent Coffee Grounds: Adsorption Property Tailoring, Batch and Packed-Bed Studies

Molecules, Journal Year: 2025, Volume and Issue: 30(3), P. 483 - 483

Published: Jan. 22, 2025

Biodiesel produced via oil transesterification often contains metallic impurities, such as copper, which affects its quality and engine performance. This study explores the use of activated carbon prepared from spent coffee grounds to remove copper biodiesel. Activated samples were biomass pyrolysis chemical activation with KOH HNO3. The optimal conditions for adsorption determined using a Taguchi L9 design. Maximum capacities 13.4 17.3 mg/g at 30 40 °C, respectively, in batch adsorbers. In packed-bed columns, axial dispersion reduced efficiency obtaining bed 1.9 5.1 under tested experimental conditions. Adsorbent characterization modeling indicated that removal was driven by multi-cationic interactions, where carboxylic groups surface acted key active sites. new adsorbent outperformed commercial bone char, making it cost-effective alternative improve biodiesel production contributing energy matrix diversification.

Preparation of CS/PVA/POP Nanofiber Membranes and Adsorption Behavior for Hg(II) Ions

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 885 - 885

Published: March 19, 2025

Chitosan (CS) and polyvinyl alcohol (PVA) nanofiber membranes were synthesized via electrospinning used as supporting materials for powdered porous organic polymer (POP). These then crosslinked with glutaraldehyde, resulting in (CS/PVA/POP) an efficient adsorbent Hg(II) ions. Characterization using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy showed that the effectively removed up to 92.9% of mercury ions at optimal conditions, adsorption capacity 116.1 mg/g. The data fit well Langmuir isotherm pseudo-second-order kinetic models. uptake was attributed chemisorption involving active groups (C=S, -NH2, -OH), facilitated by mechanisms such chelation, complexation, or exchange. CS/PVA/POP demonstrated significant advantages capacity, economic viability, recyclability, providing effective solution pollution water.
