The aim of the present study is to seta new material based on clay and its application to fix the glucose. Montmorillonite KSF-Fe2+ were prepared by varying the exchange time (3h, 8h, and 11h). These samples were identified as FM3, FM8,and FM11, respectively. Glucose level was determined using the enzymatic reaction. The adsorption kinetic of glucose, by the studied samples, showed that the FM8 gives a better fixation of glucose (40,5%). Characteristics of the samples were studied by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (IR) ,thermogravimetry (ATG) and Mossbauer spectroscopy. The X-ray diffraction (XRD) afforded the slight evolution of the interlayer distance d001 during cation exchange . The IR spectrum of FM8-G( Material loaded with glucose) show appearance of new band at 1150 cm-1 correspond to nC-O and Another band located around 1420 cm -1 is assigned dCH2+dOCH+dCCH. Thermogravimetric analysis(TGA) confirms the binding of glucose there is a loss of weight around 350°C and 410°C corresponds to the decomposition of the glucose. The study of the mossbauer spectrum of FM8 were carried out the state of oxidation of ferrous ions in montmorillonite structure. This result could confirm that the fixation of glucose was achieved successfully. keywords: Montmorillonite KSF, Ferrous ion, Adsorption, Glucose.
