New composite SBA۱۶ decorated with ZnO for water purification having Azithromycin and optimization of effective parameters by RSM method

A new mesoporous silica SBA-۱۶/ZnO was prepared by templating method using PluronicF۱۲۷ as surfactant, TEOS (tetraethyl orthosilicate) as silica source and ZnO nanoparticles as modifier. The physical properties of the materials obtained were investigated by Nitrogen sorptionat ۷۷K (BET), X-ray diffraction (XRD), Fourier transform infrared spectroscopy(FT-IR), Scanning electron microscope(SEM) and MAPPING analysis methods.The characterization results revealed thatthis new composite show highly ordered mesostructure with large surface area and pore diameter,suitable for adsorption applications for eg. antibutics. Today, presence of Azithromycin in environment can be lead to various allergic reactions. According, an effective system needs for removing these compounds. We showed that this materials can be utilizedas purification of water with low pollutant concentrations. Optimization of effective parameters on adsorption percent were performed by Response Surface Method (RSM) [۱,۲].
