Iron oxide was dispersed in a floating matrix based on autoclaved porous brick. Under an incidence of solar radiation (OH)-O-center dot radicals are generated by the photocatalytic process, completely oxidizing the organic matter. This procedure makes the proliferation of dengue larva unfeasible. Additionally, (OH)-O-center dot radicals have a remarkable deleterious effect on hatching of A aegypti eggs. The predominant iron phase was hematite (alpha-Fe2O3), as indicated by the Mossbauer spectroscopy. The formation of (OH)-O-center dot species was demonstrated by typical m/z values obtained via ESI-MS.
