Programmed liquid thermodesorption

The method of programmed liquid thermodesorption fi om the surface of studied solids can be used for calculation of the desorption energy and the desorption energy distribution function. 

Many processes and structures that are difficult to describe by means of traditional Euclidean geometry can thus be precisely characterized using fiactal geometry, for example the complex and disordered microstructures of advanced materials, adsorbents, polymers and minerals. Recent studies have shown that using fiactal dimensions enables the real sizes of pore radii to be determined and pore-size distribution functions to be calculated from the data of programmed thermodesorption of liquids [35],... 

A new method for the calculation of diffusion coefficients from Q-TG data has been presented. The programmed thermodesorption of polar and nonpolar liquids from aluminium oxide and montmorillonite-Na and -La samples under quasi-isothermal conditions has been studied. The results from above methods were compared with literature data and good correlation was obtained.
