[Study on the interaction of levofloxacin and MCM-41 by fluorescence spectrum].

The mesoporous molecular sieve MCM-41 was synthesized by hydrothermal method under microwave irradiation and the levofloxacin was encapsulated in the hexagonal ordered channels of MCM-41 using pickling process. The structure and property of MCM-41 and LVFX/MCM-41 were characterized by means of small-angle X-ray diffraction(XRD), Fourier transform infrared spectroscopy (FTIR), N2 physical adsorption, and thermogravimetric analysis-differential thermal analysis (TGA-DTA). The pore diameter and the specific surface area of the mesoporous molecular sieve MCM-41 synthesized under microwave irradiation were 2.
