Zearalenone (ZEN) is a mycotoxin produced by Fusarium species, commonly found in food, feed, and water bodies. Due to its classification as carcinogen, ZEN hazardous contaminant that requires removal from aqueous food-related effluents. To prevent release into aquatic systems, effective tertiary treatment methods are essential. This study investigates the of using two advanced technologies: adsorption photocatalysis. Two carbonaceous materials derived avocado seed residues (BC BCA) were synthesized characterized SEM, BET, XPS techniques. The capacity BC was determined be 60.23 μg g⁻1, while BCA exhibited 64.96 modeled Freundlich isotherm. Both achieved efficiencies 65 ± 5 % for 70 BCA, influenced pH, temperature, initial concentration. Photodegradation results showed 95 0.68 98 0.36 highlighting critical role light intensity degradation. underscores potential through technologies, representing significant step towards sustainable environmentally friendly remediation. Furthermore, process demonstrated reusability over 17 cycles, photocatalytic promise long-term use, with up 20 reuse cycles.

Activated Biochar from Pineapple Crown Biomass: A High-Efficiency Adsorbent for Organic Dye Removal

Sustainability, Journal Year: 2024, Volume and Issue: 17(1), P. 99 - 99

Published: Dec. 27, 2024

Renowned for its versatility in environmental applications, biochar exhibits substantial potential to enhance anaerobic digestion, facilitate carbon sequestration, and improve water treatment through highly efficient adsorption mechanisms. This study focuses on derived from pineapple crown biomass, produced slow pyrolysis, efficiency removing organic dyes contaminated water. The structural, morphological, surface properties of both chemically activated samples were comprehensively characterized using a range techniques, including XRD, FTIR, XPS, BET area analysis, SEM microscopy. performance was evaluated methylene blue (MB), rhodamine B (RhB), malachite green (MG) as model contaminants, with particular emphasis the contact time dye removal efficiency. Initial results showed rates 10.8%, 37.5%, 88.4% RhB, MB, MG, respectively. Notably, chemical activation significantly enhanced efficiency, achieving complete (100%) all tested dyes. Complete MB MG occurred within 9 min, indicating rapid kinetics. Adsorption data fit well pseudo-second-order kinetics (R2 = 0.9748–0.9999), Langmuir isotherm 0.9770–0.9998) suggested monolayer interactions between biochar. intraparticle diffusion further clarified These findings demonstrate efficacy highlight biomass remediation.

Molecules, Journal Year: 2024, Volume and Issue: 29(13), P. 3007 - 3007

Published: June 25, 2024

The United Nations proposed the Sustainable Development Goals with aim to make human settlements in cities resilient and sustainable. excessive discharge of urban waste including sludge garden can pollute groundwater lead emission greenhouse gases (e.g., CH4). proper recycling is essential for responsible consumption production, reducing environmental pollution addressing climate change issues. This study aimed prepare biochar high adsorption amounts iodine using peach wood from waste. was conducted examine variations mass ratio between (2/1, 1/1, 1/2) as well pyrolysis temperatures (300 °C, 500 700 °C) on carbon yield capacities biochar. Scanning electron microscopy, Brunauer–Emmett–Teller analysis, Fourier transform infrared spectrometry, powder X-ray diffraction, elemental analysis were used characterize produced at different ratios. results indicate that found be highest (>60%) a temperature 300 °C across temperatures. absorbed aqueous solution ranged 86 223 mg g−1 1:1 wood, which comparably higher than those observed other advances water treatment by offering cost-effective method derived processing
