NaY Zeolite was synthesized from sodium-aluminate solution from the Bayer process, water glass and mineral acids HCl, H2SO4, HNO3 and H3PO4 acids were used in order to reduce the concentration of Na+ ions to the mole ratio that will enable the formation of NaY Zeolite. The reaction mixture for the synthesis of NaY Zeolite had the following composition: 2Na2O : Al2O3 : 6,5SiO2: 120H2O. The synthesis was conducted with the addition of “seed gel“ using hydrothermal method. Crystallization lasted 24 hours at the temperature of 100°С. The samples obtained were subjected to mineralogical and chemical analysis. Мineralogical analysis, obtained by x-ray diffraction, showed that, for the identical conditions of synthesis, NaY zeolite was obtained in those sytheses in which H2SO4, HNO3 and H3PO4 were used, whereas the synthesis using HCl resulted by occurrence a transitient amorphous phase without the presence of NaY zeolite crystals.

MNK Publication was founded in 2012 to upholder revolutionary ideas that would advance the research and practice of business and management. Today, we comply with to advance fresh thinking in latest scientific fields where we think we can make a real difference and growth now also including medical and social care, education,management and engineering.
We offers several opportunities for partnership and tie-up with individual, corporate and organizational level. We are working on the open access platform. Editors, authors, readers, librarians and conference organizer can work together. We are giving open opportunities to all. Our team is always willing to work and collaborate to promote open access publication.
Our Journals provide one of the strongest International open access platform for research communities. Our conference proceeding services provide conference organizers a privileged platform for publishing extended conference papers as journal publications. It is deliberated to disseminate scientific research and to establish long term International collaborations and partnerships with academic communities and conference organizers.
