The Investigation of Kinetic Characterization of Sea Salt via Thermoluminescence Method

The calculation of the kinetic parameters of a thermoluminescence material (kinetic order (b), activation energy (E) and frequency factor (s)) by using the thermoluminescence (TL) method is extremely important in determining the kinetic characterization of the materials. Sodium Chloride (NaCl) is an inorganic salt. It is a crystal well known for its luminescent properties, with a simple cubic structure and its band gap is rather large (~ 8.5 eV). In this work, it was reported the TL response of the material in the range of 50– 400 oC and calculated kinetic parameters of sea salt. Two glow peaks were observed at 100 oC and 235 oC in the TL glow curve of sea salt with a heating rate 2 oC/s after X-ray irradiation. The Tm-Tstop method was used to determine the overlapping peaks under the main peak at 100 oC. With the computerized glow curve deconvolution (CGCD) method, the peak analysis was performed. In addition, kinetic parameters were calculated using various heating rates and peak shape. The b = 1.5, E = 0.88 eV and s = 1.7x1011 s-1 values were calculated using the peak shape method
