The hydroxyl-Fe pillared montmorillonite complexes at different OH/Fe molar ratios(i.e., 0.6、0.8、1.0、1.5 and 2.0 OH/Fe montmorillonite) were prepared with purified montmorillonite samples(K10) as raw materials. The adsorption interaction of aminoglycoside antibiotics with both OH/Fe montmorillonite and K10 were investigated at various pH values of sorption solution and time on the adsorption of the OH/Fe. The adsorption materials were analyzed by X-ray diffraction,Fourier transformed infrared spectoscopy an...
