How β-cyclodextrin- loaded mesoporous SiO₂ nanospheres ensure efficient adsorption of rifampicin.

ABSTRACT: In this study, β-CD@mesoporous SiO₂ nanospheres (β-CD@mSi) were prepared by loading β-cyclodextrin (β-CD) onto mesoporous silica nanospheres through an in situ synthesis. This not only solved the defect of β-CD being easily soluble in water, but also changed the physical structure of the mesoporous silica nanospheres. FTIR and XPS results showed that β-CD was successfully loaded onto mesoporous silica nanospheres (mSi), while enhancing the adsorption effect. β-CD@mSi with a monomer diameter of about 150 nm were prepared. At a temperature of 298k, the removal efficiency of a 100 mg/L solution of rifampicin can reach 90% in 4 h and the adsorption capacity was 275.42 mg g^-1 at high concentration. Through the calculation and analysis of adsorption kinetics, adsorpt
