The utilization of renewable materials has raised worldwide interest regarding biodegradable polymers, proving important scientific, ecological, and economic relevance. Biopolymers are versatile materials used in various applications due to their high strength, low weight, and minimal environmental impact. However, their characterization for understanding their properties requires extensive experimental measurement. In this context, conventional research is improved by the integration of artificial intelligence (A...

Biochar can be used as an alternative and efficient adsorbent for organic and inorganic pollutants. Therefore, based on previous study in which, a biochar loaded with mixed metal oxides of iron, tin or titanium catalysts results as a by-product of levulinic esters synthesis from biomass carbohydrates, this paper aim was to test this residue as biochar for the retention of phosphate from water samples. The obtained adsorbents based on Fe2O3-SnO2 and Fe2O3-La2O3-TiO2 were characterized by FT-IR and TGA analyses. The...

The presence of nitrate concentration in drinking water can cause high toxicity to the human body, being considered among the most important pollutant in the environment. Among the many methods available such as biological treatment, electrodialysis, reverse osmosis, adsorption, ion exchange, adsorption is the most used technique due to its low cost and simplistic design. Therefore, the aim of this paper was to study the retention of nitrate anion from high concentration aqueous solutions on a novel magnetic adsor...
