This study presents a sustainable approach to activated carbon production from olive stones in comparison commercial ones, using various activating agents such as H3PO4, KOH, and ZnCl2, for enhancing the adsorption properties versatile capability remove range of pollutants including copper ion, methylene blue, 2,4-Dichlorophenoxyacetic acid aqueous solutions. The performances carbons across varying conditions pollutant concentrations, temperatures, pH levels, adsorbent amounts were tested. Increased initial concentrations correlated with higher capacities. Maximum capacities achieved at levels 5, 10, 2 Cu, MB, 2,4-D, respectively. For KOSAC, Cu removal rose 27 % 52 %, ZOSAC, MB increased 39 65 2,4-D surged 33 99 amounts. Model validation was carried out utilizing kinetic models (PFO, PSO) isotherm (Langmuir, Redlich-Peterson). PFO model Langmuir proved more suitability adsorption, whereas PSO models, along Redlich-Peterson prominent adsorption. Thermodynamic analysis revealed that exothermic, while endothermic. By optimization experimental conditions, maximum attained 30.34 °C 297.65 mg L−1 KOSAC-Cu, 48.62 269.37 ZOSAC-MB, 30.31 299.02 ZOSAC-2,4-D sorption. research highlights ZOSAC's potential cost-effective, eco-friendly solution water treatment, contributing environmental sustainability economical feasibility.

Reinforcement using undoped carbon quantum dots (CQDs) with a partially carbonized structure doubles the toughness of PVA membranes

Nanoscale Advances, Journal Year: 2024, Volume and Issue: 6(6), P. 1750 - 1764

Published: Jan. 1, 2024

Nano-carbon-reinforced polymer composites have gained much consideration in functional applications due to their attractive mechanical strength and cost-effectiveness. The surface chemistry associated of carbon nanotubes (CNTs), graphene, other derivative-based nanocomposites are well understood. While CQDs considered emerging derivatives, chemistry, unique physio-chemical properties, dispersion behavior polymers yet be explored. Therefore, this work, with different structures were synthesized from lemon pulp urea, rheology studied the PVA matrix. structure controlled using solvents reaction temperatures, respectively. possessed a circular shape, size <10 nm, having suitable core groups, as confirmed by TEM FTIR spectroscopy. dynamic viscosity particle PVA/CQDs films peaked at 4% inclusion maximum crosslinking U-CQDs reinforcement 180 °C. Compared pure PVA, optimized composite showed an 80% larger 67% better tensile concentration. In addition enhanced strength, exhibited antibacterial activity composites. These CQDs-reinforced may for textile (shape memory photo-active textiles).
