Hydrothermal Synthesis of Nano Crystals (A.M.) Zeolite using Variable Temperature Programs

Objective: The synthesis and characterization of (A.M. zeolite) was designed for the unique cation exchange, adsorption, hydrationdehydration, catalytic properties, soil remediation, could be load with macro& micronutrients, and become slow-release fertilizer. Methods: The zeolite was hydro thermally synthesized by varying the concentrations of Si and Al at different crystallization temperature. Different visual instrumental techniques were used to characterize the product of nano (A.M. zeolite) which obtained at different synthesis parameters using X. ray diffraction, FTIR (fourier transform infrared spectroscopy), TEM (transmission electronic microscope), SEM (scan electronic microscope), TGA (thermogravimetric analysis) and TDA (differential thermal analysis), CEC (cation exchange capacity) and AEC (anion exchangeable capacity). Results: The temperature was found to be a crucial factor for the control of the crystal size. Broad and sharp peaks obtained in diffractogram shows the amorphous and crystalline nature of the materials respectively. We found that, the composition of (A.M zeolite) was approximately close to the concentrations of the precursors taken during synthesis. The FTIR spectra of these A.M. zeolites in framework vibration region also shows sharp feature for A.M zeolite. High crystalline nature of the material is reveals by absorption bands. On the other hand, BET illustrate that AM zeolite had a high value of surface area at 1000ºC and nano pore size distribution. CEC recorded high value, while AEC gave lowest value. EDX results showed that, Si/Al ratio for AM Nano zeolite tends to be hydrophilic. Conclusion: We can conclude that, synthesized A.M. nano zeolite can potentially be used in industries, conventional agriculture, horticulture, environmental protection, safety agriculture, biomedicine proposes and water retention and purity specially in arid zones.
