Abstract

In this paper , TiO2 impurities exists in kaolin were investigated for the first time as an active centers for photo degradation of M.B ( Methylene Blue) dye. The study extends to examine the same impurities after its transformation into NaP zeolite. Simultaneous removal of heavy metals (Pb2+, Cu2+, Ni2+, Co2+) in presence of organic dye over metakaolinite phase and NaP zeolite was performed in presence and absence of UV irradiation.
The samples were characterized using XRD, SEM , EDX, Diffuse UV-Vis spectrophotometer and finally drawing the kinetic curves of removal of heavy metal ions and M.B dye. The results showed that the TiO2 impurities in metakaolinite exists in anatase form and maintain its existence in the transformed Na-P zeolite with the same phase. Both NaP and metakaolinite showed photo catalytic activity towards degradation of M.B dye. However, the NaP zeolite showed superior behavior for simultaneous removal of both pollutants with UV Irradiation. Investigation and mode of removal of both samples were investigated.
