| dc.description.abstract | With growing issue of the abundance of coal fly ash throughout the world that occupy landfills by creating both environmental and health problems, the requirement for an effective utilization method is constantly growing. Another issue that also needs to be tackled is the contamination of water with hazardous metals and radioactive ions, such as Hg2+ and I-. There is a huge interest of research community in conversion of coal fly ash into zeolites and composites. The impetus is on the optimization of its production process and modification with silver nanoparticles. This, however, requires a thorough understanding of coal fly ash zeolitization conditions and mechanisms. The preferred route of the synthesis of zeolites is the hydrothermal treatment of coal fly ash in a strong alkali solution at elevated temperatures, followed by doping of silver nanoparticles. The process involves several parameters, such as reaction temperature, time, the concentration and L/S ratio, Si/Al ratio in coal fly ash. These parameters appear to have an arbitrary effect on the yield of zeolite and the nanocomposite produced thereof. We propose a conversion model using the fuzzy system and optimize the zeolitization process. The model is designed and developed, using the data, both from literature and experiments, and is later optimized to provide accurate inferences. Further, the doping of silver nanoparticles to produce nanocomposites and using the novel nanocomposite for efficient remediation of Hg2+ and I- from water to study the mechanism by multiple advanced characterization methods.... | en_US |
