Abstract : Removal of Water Pollutants Over Synthetic Microporous Materials By: Reham M. Ben Dekhail Supervised By: Dr. Qana Alsulami Dr. Eman Hegazy ABSTRACT Different zeolites of various framework topologies were synthesized by hydrothermal treatment of Saudi Kaolin and Sodium Hydroxide under autogenous pressure with various conditions. Saudi Kaolin was the starting material. Hydroxy Sodalite, Nephline hydrate, and Y zeolite were characterized using XRD, SEM, and EDX. Moreover, Incorporation of Ti into framework of HS was performed within the same preparation conditions. SEM and EDX analysis in addition to XRD lattice analysis proved the successful incorporation of Ti. For this study, MB combined with a set of Co2+, Cu2+, Ni2+and Pb2+ ions were used for examining the removal efficiency of the prepared zeolites. Simultaneous removal of heavy metals in the presence of organic dye over HS, HS+Ti, NH, and Na-Y was performed in the presence and absence of UV irradiation. In order to fully characterize the removal of such a system over prepared zeolites, the three-dimensional graphs were drawn. The HS+Ti gave similar removal behavior to HS but with less photodegradation behavior. NH showed photodegradation of dye higher than HS, Although removal capacity of NH lesser than that of HS. Also, the photoaffinity of different samples towards dye was calculated. HS has a high photodegradation affinity that increases as the amount of ions increase, the same behavior with HS+Ti but with less photodegradation affinity <30%. In contrast, the NH has less photodegradation affinity which means more absorption power. Na-Y too followed the same behavior but with higher photodegradation affinity percentage.
