A novel porous adsorbentbased on cactus powder/ionic liquid for the removal of nimesulide from wastewater.

This work proposes the fabrication of a novel adsorbent based on agro-waste resources with functional adsorption properties to remove a recalcitrant pollutant, such as Nimesulide, from water effluents. An aerogel system, produced through supercritical carbon dioxide drying, was made of cactus powder and 1-ethyl-3-methylimidazolium dicyanamide ionic liquid. The use of ionic liquid allowed to obtain a 3D porous structure showing a mean pore size of 0.

Adsorption of Safranin O Dye by Alginate/Pomegranate Peels Beads: Kinetic, Isotherm and Thermodynamic Studies.

Water pollution is regarded as a dangerous problem that needs to be resolved right away. This is largely due to the positive correlation between the increase in global population and waste production, especially food waste. Hydrogel beads based on sodium alginate (Alg) and pomegranate fruit peels (PP) were developed for the adsorption of Safranin O dye (SO) in aqueous solutions.
