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

Published: April 15, 2025

Contamination of water resources with organic pollutants is a serious environmental problem. Degradation using photocatalytic materials promising method wastewater treatment. In this work, we report on the fabrication novel 3D printed (3DP) ZnO/Clay to be used as efficient photocatalysts for degradation methylene blue (MB). Extrusion-based direct ink writing technology was utilized print scaffolds. The synthesized scaffolds were thoroughly characterized analytical techniques Brunauer-Emmett-Teller, Fourier transform infrared, X-ray diffraction, scanning electron microscopy, and energy-dispersive spectroscopy. activity studied by measuring photodegradation MB under simulated solar radiation. synergistic effects adsorption resulted in 100% removal efficiency within 40 min 3DP catalyst. reported catalysts require minimum time high efficiency, therefore, no further treatment required after usage catalytic experiment. also demonstrated excellent stability during reusability test, where performance assessed several consecutive cycles without any or regeneration. This work can provide way preparing environmentally friendly photocatalysts.

Biocomposite Based on Polyhydroxybutyrate and Cellulose Acetate for the Adsorption of Methylene Blue

Journal of Composites Science, Journal Year: 2024, Volume and Issue: 8(7), P. 234 - 234

Published: June 24, 2024

Industrialization and globalization have caused severe environmental problems, such as contaminating water bodies by toxic agents from various industries, generating a significant loss of biodiversity health risks. Globally, approximately 80% wastewater is discharged without treatment, worsening the situation. However, in Colombia, initiatives been taken to improve management, with ambitious investments targets treatment infrastructure. Recently, advanced technologies developed treat wastewater, including more efficient sustainable biological methods, using coconut-derived adsorbent biomaterials, rich useful properties for adsorption pollutants solutions. This research focuses on developing composite biomaterial cellulose acetate (CA) extracted coconut mesocarp polyhydroxy butyrate (PHB), casting method, wastewater. Adsorption tests tracer methylene blue (MB) were carried out Energy Environment laboratory University Cartagena. For this, MB solutions prepared 5 50 ppm concentrations. The analyses showed that thermally stable has good homogeneity porosity. At concentration 40 dosage 10 mg adsorbent, efficiency was 89%, an capacity 35.98 mg/g. above indicates presented sustainable, improved, solution remove contaminants benefiting environment human health.
