In the present paper, the sample preparation is carried out by combustion assisted method, chemical root method and solid root method. The X-ray spectroscopic setup is available at Raja Ramanna Center for Advanced Technology (RRCAT), Indore, India and is called dispersive EXAFS beamline BL-8.The X-ray absorption spectra have been recorded using synchrotron radiation. This beamline has been recently commissioned at the 2.5 GeV Indus-2 synchrotron radiation sources. The theoretical XANES and EXAFS spectra have been calculated using BL-8 data then use some mathematical method like Levy's Method, Lytle's Method, L.S.S. Method and Fourier Transform (FT) Method. In XANES region we find out the values of Cu K –edge, sample K-edge,edge width, chemical shift,shift of principal maxima, percentage covalency and effective nuclear charge .In EXAFS region we find out the value of bond length of all the mathematical methods.
