    The aim of this study is to verify the amount of nitrate absorption on Latium composite over active carbon in which pH parameters, temperature, pollutant concentration, contact time for absorbent were considered. It was determined that optimum condition for absorbent are pH=3, T= 0 ˚C and initial concentration of solution=10 ppm, then absorption parameters verified and after drawing absorption isotherms (Langmuir, freundlich) in nitrate absorption process it was evident that languir model had the most conformity with experimental data gained Latium composite on active carbon.

    In this study the reaction of the derivative , material [1,5-b] tetrazolo [1,2,4] Terry inflorescences (TTA) with boron nitride nano- cages in different conditions of temperature , density functional theory methods were studied . For this purpose, the material on both sides were geometrically optimized reaction , then the calculation of the thermodynamic parameters were performed on all of them . The values ​​of ΔH, ΔG, ΔS the reaction at different temperatures for different products together, these parameters in the raw material is obtained . And finally, the best temperature for the synthesis of derivatives of explosives, according to the results of thermodynamic parameters were evaluated.
    Keywords: Enthalpy of formation, (TTA), boron nitride cage
