Abstract

The present research project is a continuation of completed research projects (Fapesp #2018/05698-0, Fapesp #2019/09991-6 and IFSP-PRP Public Call 823/2018), of an ongoing research project (Fapesp # 2018 / 17913-2), and the search for the closure of a hybrid technology capable of removing amoxicillin from a drug dissolved in water. Therefore, it is proposed to intensify processes for the removal of amoxicillin in water with the O3/H2O2-Adsorption technologies in an alkaline medium (pH e 9.0). The alkaline medium, in addition to providing greater solubility of amoxicillin in water, hydroxyl (OH^-) participates in mechanisms for the generation of radicals (*OH) from auxiliary oxidants O3 and H2O2 in water, even in the absence of low-pressure germicide lamps. As a highlight of the project, there is the application of Moringa oleifera seeds purified by protocols adapted by our research group. There is not a single work published in the literature that involves the removal of amoxicillin from a commercial formulation in water by adsorption mechanisms with Moringa oleifera seeds, much less as a complementary process to advanced oxidative processes. The project will be developed by the student responsible for adapting the moringa purification protocol (IFSP-PRP Edital 823/2018) and who informally helped the Fapesp project #2019/09991-6.
