Adsorption of ibuprofen molecule onto mesoporous silica SBA-15 loaded by iron particles using arc discharge treatment

Abstract

In this article, adsorption performance of mesoporous silica SBA-15 loaded by iron particle via arc discharge methods has been investigated for the first time using ibuoprofen as molecule adsorbate model. The block copolymer poly-ethyleneglycol-block-poly-propylene glycol-block-poly-ethylene glycol P123, tetraethoxysilane and chloride acid has been acted as nano templating, silica source and catalyst during preparation of mesoporous silica SBA-15. The mesoporous silica SBA-15 has been synthesized by hydrothermal technique which is followed by arc discharge iron treatment for adding magnetic character. Transformation of mesoporous silica structure has been investigated by small angle X-ray diffraction (XRD), scanning electron microscopy (SEM) and nitrogen adsorption-desorption techniques, Fourier-transform infrared spectroscopy (FTIR) and elemental analysis. The result showed that magnetic properties mesoporous silica SBA-15 increased after arc discharge treatment without significant structural damages. The ibuprofen adsorption prepared by using 20 mg adsorbent dose and time for contact between adsorbent and adsorbate in 100 min at room temperature. The adsorption capacity of mesoporous silica SBA-15 investigated by UV-Vis show that maximum adsorption capacity of SBA-15 was up to 77.5 mg.g−1 on optimum condition.
