Effective removal of pollutants from industrial effluents in order to restore these waters to the cycle, and also from the environmental point of view is very important.  BTEX is an indicator of Volatile Organic Compounds (VOCs).  In this study, the BTEX adsorption method was applied to the MOF-199 nano-absorbent. the MOF-199 was initially synthesized by hydrothermal method and characterized by XRD, FE-SEM, and BET analyses. Adsorption test was performed under NPT conditions and HPLC technique was used for analysis, which confirmed the experimental results of absorption. The equilibrium adsorption isotherms were plotted at 298 ° K. According to the results, the BTEX adsorption isotherm with MOF-199 can be detected with Langmuir isotherm as well as Freundlich isotherm. by comparing the values of the maximum adsorption capacity (qmax) of compounds, the amount of MOF-199 adsorption capacity for benzene and xylene was 108.695 (mg/g), and for ethylbenzene and toluene, 107.526 and 83.333 (mg/g) was obtained, respectively.
