Abstract :

Background and Objective: Nano material has attracted much attention due to its functional groups and special properties. In this study, silica nanoparticles immobilized on zeolite 13X granules (SZX13), by sol gel method was synthesized. The aim of this study was determination of the performance of prepared nano sorbent in nickel ions removal from aqueous solution. Material and Methodology:The present historical research, with an analytical-comparative approach, has used inferential and deductive reasoning. First, the principles of organic style architecture, derived from a comparative study of written evidence and existing documents, were explained as a criterion of measurement. Then, a list of works of organic architecture in Iran was prepared to select samples for analysis by purposive sampling. Finally, the analyzed samples were compared with the principles of organic architecture. Findings: Scanning Electron Microscope analysis showed that the immobilization process was successfully carried out and the immobilized particles has a nano size distribution. Optimized values for each factor to achieve the highest uptake were found to be as follows: The Ni initial concentration of 60 mg/L, the pH 6, the adsorbent (SZX13) dose of 1 g, at 40 ° C. Discussion and Conclusion: Results showed that the immobilization of nano particles on the zeolite not only led to that the particles were distributed in an expanded volume, but also prepare the accessible usage of that in an industrial scale. In addition, with immobilization of silica nanoparticles onto zeolite granules, the sorption of nickel ions were increased in comparison to that by using zeolite 13X, and the removal percentage was increased from %26 to %43.98.
