Rice Husk Derived Nano Zeolite (A.M.2) as Fertilizer, Hydrophilic and Novel Organophillic Material

Abstract

The investigation aimed to convert mixture rice husk with aluminum foils (as houses and restaurants wastes) into Nano Zeolite (NZ) enrich by elements, safety, and eco-friendly fertilizer using calcinations and zeolitization processes. The end product has undergone various techniques: Crystallization, phases, physic-chemical characteristics and surface morphology were studied. Transmission electronic microscope (TEM) appeared the crystals of NZ in nano size (uncontrolled growth particles), using scanning electron microscope (SEM) coupled with energy dispersive spectroscope (EDS) showed that NZ gave different shapes and size during calcinations process, Stereo microscope illustrated that, the crystals growth of NZ were in three dimensions and take different shapes after calcinations and zeolitization processes. X-ray diffraction (XRD) recorded that the dominant mineral was zeolite with accessories minerals. X-ray fluorescence (XRF) was used to verify the type of NZ and whether if it is hydrophilic or hydrophobic. Furthermore, the XRF revealed a high composition of silica and alumina in Nano material with high Si/Al ratio, potassium and calcium were the major single extra-framework cations in NZ. Surface area values, pore sizes distribution, pore volume, pore width, two and three dimension images and roughness particles were estimated using atomic force microscope (AFM). The highest CEC value of NZ was recorded. Light microscope showed that, nitrogen fixing and phosphorus solubilizing bacterial cells were existing on NZ particles as novel carrier material (consider as organophillic). In addition to previous analyses, dielectric and electrical properties measurements were examined for NZ particles using broadband dielectric spectroscope (BDS). NZ particles have been proved to be hydro-cracking, has characteristics of Faujasite family and could enrich soil fertility and improve plant growth particularly in arid and semi arid zones.
