The increased detection of pharmaceuticals in finished drinking water has become a growing cause of concern in recent years. The removal of atenolol, ranitidine, and carbamazepine by sepiolite, following functionalization of its surface by organosilane grafting, constituted the subject of this investigation. Silylated surfaces include octyl,...

The use of pesticides in agriculture is essential because it reduces the economic losses caused by pests, improving crop yields. In spite of the growing number of studies concerning the development and application of controlled release formulations (CRFs) of pesticides in agricultural soils, there are no studies about the effects of such...

The objective of this work was to develop emulsions containing lemongrass essential oil and Appyclean 6552 (emulsifier). The emulsions were prepared using two different processing techniques: microfluidization and sonication. A decrease in Sauter diameter with ultrasonic power and residence time in sonicator was observed, reaching values of 195...

Cyanobacterial blooming episodes in surface waters used for drinking purposes are increasing due to eutrophication of water ecosystems. Water treatments should be optimised to remove phytoplankton cells as well as their associated toxins. The performance of a multicell electrocoagulation reactor operating under a continuous flow and coupled...

Slow release formulations of the herbicide imazaquin (2-(4-isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)quinoline-3-carboxylic acid) were prepared by its adsorption on Fe-pillared clay minerals (Fe PILCs). Fe PILCs were synthesized by the reaction of Na+-montmorillonite (SWy-2) with base-hydrolyzed solutions of Fe and Al. The...
