Investigation of CO₂ Adsorption on Modified Bimetallic Activated Carbon Derived from Apricot Stones

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 3, 2025

The adsorption of CO2 was investigated on monometallic and bimetallic activated carbon (PAC) prepared from apricot waste. Metals such as Zn, Ni, Ce, Cu were impregnated onto PAC at varying ratios. Scanning electron microscopy images revealed grain-like particles flower-like layers due to the accumulation metals. N2 sorption analysis (BET) showed an increase in surface area 756.95 m2/g after modification with Zn. For adsorbents, addition Ce resulted areas 753.95 731.91 m2/g, respectively. Pore size distribution indicated presence micropore channels 1-2 nm range for both adsorbents. tests demonstrated that metal impregnation enhanced capacity. 0.5Ce/0.5Zn/PAC sample exhibited highest capacity, reaching 4.25 mmol/g 0 °C 2.77 25 °C. heat 0.5Ce0.5Zn/PAC ranged 31.4 41.3 kJ/mol, suggesting is predominantly physical. A two-cycle regeneration test a reduction uptake ranging 5.1 9.7%, indicating high adsorbent stability. also selectivity over N2. Kinetic studies intraparticle diffusion model best fits experimental data. capture system developed this study shows potential applications outlets production processes gas purification facilities.

Amoxicillin adsorption onto oil palm trunk‐derived activated carbon: synthesis optimization, modelling of mass transfer and ultrasonic regeneration

Journal of Chemical Technology & Biotechnology, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Abstract BACKGROUND Antibiotics such as amoxicillin (AMC) can persist in the environment due to their stable molecular structures. This study aimed (i) optimize synthesis of oil palm trunk‐based activated carbon (OPTAC) for AMC removal, (ii) model adsorption process using mass transfer (MTM) and (iii) evaluate OPTAC regeneration through ultrasonic washing. was synthesized potassium hydroxide activation followed by dioxide treatment. RESULTS Response surface methodology (RSM) identified optimal conditions at 343 W, 12.87 min an impregnation ratio 2.00 g −1 . Under these conditions, predicted uptake 146.44 mg (actual: 154.15 ; 5.00% error), yield 42.78% 41.19%; 3.86% error). The AMC–OPTAC Freundlich isotherm, with a Langmuir capacity ( Q m ) 238.67 Kinetic analysis revealed that pseudo‐first‐order best described system. MTM yielded average constant k 0.23 L h , rate 0.00051 estimated area 611.34 2 closely matching measured mesopore (647.82 5.63% Thermodynamic confirmed physisorption dominant mechanism, spontaneous endothermic behavior.
