In this study, hybrid magnet-sensitive nanoparticles made by magnetite and humic acid are primarily obtained following a co-precipitation route. Subsequently, such hybrid systems are fully recycled following a two-step process, namely: (i) calcination under air (oxidizing) atmosphere, and (ii) acid digestion to obtain an Fe(III) aqueous solution. After neutralization, hybrid magnet-sensitive nanoparticles are re-synthesized following a properly modified synthetic route analogous to the previous one. Both hybrid nanoparticles are characterized by means of different morphological, structural, physicochemical, and magnetic techniques. Additionally, these magnet-sensitive hybrids are tested in the photocatalytic abatement of paracetamol from model wastewater, investigating a photo-Fenton degradation route. Experimental results evidence a superimposable degradation profiles of both hybrid nanoparticles, with an …
