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 1150cm^-1 correspond to nC-O and Another band located around 1420 cm ^-1  is assigned d CH₂+d OCH+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 MÖssbauer  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
