Formation of boron – silica based mesoporous and studies of its adsorption ability for curcuminoids

Abstract

The development aims of mesoporous silica formation in pharmaceutical fields were its uses as a drug delivery vehicle and in separation. It is possible because of the large particle surface area, the presence of pores, and the possibility to modify functional groups in the mesoporous materials. In this study, the formation of silica-based mesoporous and boron-silica-based mesoporous materials was carried out by sol-gel techniques and modification of functional groups was carried out by the co-condensation method. Mesoporous material characterization was carried out using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR). Adsorption ability of curcuminoid onto the mesoporous was carried out through isotherm adsorption study approaches using adsorption models including Langmuir, Freundlich, and Temkin model. The results of the isotherm adsorption study showed that the Freundlich model is the best model for isotherm adsorption with an r2 value of 0.997.
