Abstract
The preparation of a series of different Ti/Zr MEL structure was performed successfully. Full characterization of the prepared materials was done using XRD, IR, DR, and SEM. The results show that the prepared materials contain only one crystalline phase (ZSM-11). The affinity of Zr to form the crystalline phase alone in a binary Zr/Ti synthesizing mixture was approved by SEM and elemental analysis results. The percentage of each active site was calculated. DR spectra were deconvoluted, and three active sites were supposed and quantified (tetragonal, octahedral, and crystalline). The mutual effect of ions (lead, copper, cobalt, and nickel) and methylene blue dye on the removal efficiency with and without ultraviolet irradiation was examined and fully characterized. The ions largely influence the photodegradation process, and a mechanism was formulated. Meanwhile, the presence of dye showed a negligible effect on the removal of ions.

Zeolite Socony Mobile 11 or ZSM-11 with a bi-dimensional ten-ring pore system structure is still attracting more and more attention, its first patent by Mobil OilCompany in the 1970s [1]
For example, the incorporation of vanadium into an analcime structure resulted in increasing the removal capacity for heavy metal through its inclusion as an octahedral species rather than the usual isomorphs substitution of Si in tetrahedral positions [11]
In order to examine the prepared materials in the simultaneous removal of organic inorganic pollutants, a series of experiments were performed using different concentration and inorganic pollutants, a series of experiments were performed using different concen2+, Cu2+, Ni2+, Co2+ ) and methylene blue dye as an example of organic pollutant of ions (Pb tration of ions (Pb2+, Cu2+, Ni2+, Co2+) and methylene blue dye as an example of organic over the prepared blue dye is blue an example of example cationic dye, which may pollutant over thematerials
Summary
Zeolite Socony Mobile 11 or ZSM-11 with a bi-dimensional ten-ring pore system structure is still attracting more and more attention, its first patent by Mobil Oil. The removal of pollutants, especially organic dyes and heavy metals, is still considered to be challenging work. The purpose of treatment is the removal process, but it is extended to include many environmental restrictions either for the methods and/or effectiveness. Among many methods of removal, the photodegradation of organic pollutants is environmentally safe; it uses only light and non-poisonous photocatalyst. It attracts special interest when it uses the direct sunlight in removal [19]. For the first time, the preparation of only a Ti-Zr MEL structure with the. This is the first to first study such system forathis purpose
