摘要

Abstract

The adsorption of mesoporous Fe

-SiO

-TiO

(MFST)

which can be separated easily from solution by a magnet

for the removal ofmethyl orange (MO)was investigated. The nitrogen adsorption-desorption measurement shows successful synthesis of MFST with an average pore size of 3.8 nm and a large specific surface area of 55 m

. About 95% adsorption percentage of MO is achieved with an initial concentration of 10 mg·L

in the dark and the MFST exhibits superior adsorption ability under acid conditions. The adsorption data fit well with the pseudo-second order model for adsorption. After 4 cycles

the adsorption rate for MO remains 74% in the dark and the MFST can be recovered in a magnetic field with a recovery of about 80% (by mass). It demonstrates that the samples have significant value on applications of wastewater treatment.
