“…This phenomenon could explain the high adsorption values of RB19 (negative charge) on PEIcoated magnetite (high positive zeta potential) and the moderate adsorption values for the other type of nanoparticles, with absolute surface charges below 15 mV. Furthermore, negative zeta potential values were reportedly shown to contribute to H 2 O 2 decomposition, favoring the concentration of H 3 O + near the surface and promoting radical formation [34]. However, the high interaction between PEI-coated magnetite and RB19 is not related to high degradation rates, as a high adsorption value may lead to saturation of the catalyst surface and consequently, to slower kinetics.…”

In recent years, the application of magnetic nanoparticles as alternative catalysts to conventional Fenton processes has been investigated for the removal of emerging pollutants in wastewater. While this type of catalyst reduces the release of iron hydroxides with the treated effluent, it also presents certain disadvantages, such as slower reaction kinetics associated with the availability of iron and mass transfer limitations. To overcome these drawbacks, the functionalization of the nanocatalyst surface through the addition of coatings such as polyacrylic acid (PAA) and their immobilization on a mesoporous silica matrix (SBA15) can be factors that improve the dispersion and stability of the nanoparticles. Under these premises, the performance of the nanoparticle coating and nanoparticle-mesoporous matrix binomials in the degradation of dyes as examples of recalcitrant compounds were evaluated. Based on the outcomes of dye degradation by the different functionalized nanocatalysts and nanocomposites, the nanoparticles embedded in a mesoporous matrix were applied for the removal of estrogens (E1, E2, EE2), accomplishing high removal percentages (above 90%) after the optimization of the operational variables. With the feasibility of their recovery in mind, the nanostructured materials represented a significant advantage as their magnetic character allows their separation for reuse in different successive sequential batch cycles.
