In this study was synthesized MCM-41 mesoporous silica by hydrothermal treatment and funtionalized with titanium in order to obtain mesoporous materials with high surfacea area and photocatalytic activity in photodegradation of organic compounds as antibiotics. The functionalization of the synthesized support material was achieved by impregnation from alcoholic solution. The obtained materials (MCM-41) and (Ti-MCM-41) were characterized by X-ray diffraction (XRD), scanning electron microscopy (S...

This study investigates the mechanism and efficiency of catalytic ozonation process on iron-loaded rice husk ash (Fe-RHA) and Peanut shell ash (Fe-PSA) for the Erythromycin removal from aqueous solution. In the current study, the COD removal efficiency of Erythromycin was studied in simple ozonation and catalytic ozonation using Fe-RHA/O3 and Fe-PSA/O3 processes. The operational parameters such as pH effect, catalyst dose, and reuse performance of the catalyst were studied. Moreover, the hydroxy...
