dc.description.abstractCarbamazepine (CBZ) is an endocrine disrupting and psychoactive chemical. The application area of this chemical is wide and the presence of CBZ concentration in water is very high. The half life of CBZ is 25 - 65 h. So, purification of water from CBZ is a very important issue. In this study, adsorption method was used for this purpose. UiO-66 (Universitetet i Oslo) is one of the most popular metal organic frameworks. The adsorption ability of UiO-66 is very high. UiO-66 and graphene nanoplatelet (GNP)/UiO-66 composites were prepared by hydrothermal method. Then, XRD, FTIR, SEM, surface area and particle size distribution methods were applied for characterization of nanoparticles. The prepared adsorbents were used for CBZ adsorption. Some adsorption parameters were tested. These parameters are amount of adsorbent, volume of adsorbate, pH of solution, contact time of solid and liquid phase and initial CBZ concentration. Pseudo first order kinetic model and pseudo second order kinetic model were applied to contact time data. Non-linear Langmuir isotherm and non-linear Freundlich isotherm were applied to initial CBZ concentration experimental data. Also, these isotherm studies were repeated for different temperatures, 20 degrees C, 25 degrees C, 30 degrees C, 40 degrees C and 50 degrees C. According to Langmuir isotherm, maximum CBZ adsorption capacity of UiO-66 nanoparticles were calculated as 16.69 mg/g, and maximum CBZ adsorption capacity of UiO-66/GNP nanoparticles were found as 51.17 mg/g.en_US
