Confiscation of aromatic compounds. Microwave synthesized electrolyte treated and Si/Al enhanced mesoporous zeolitic materials originated from sugar industry detritus

Doctoral Thesis / Dissertation from the year 2016 in the subject Chemistry - Analytical Chemistry, grade: 82.5, Gujarat University, course: Chemistry, language: English, abstract: The aim of this research was to synthesize and study batch properties of zeolite synthesized from Bagasse fly ash and its derived zeolitic material. To achieve this, a study was carried out with the following objectives. To synthesize zeolites from Bagasse fly ash solution via microwave assisted hydrothermal synthesis process. To study the effect of adding electrolyte and electrolyte with sodium silicate to BFA solution towards the development of zeolitic material. To investigate the effects of adding sodium hydroxide and sodium hydroxide plus sodium meta silicate for activation of BFA. To examine the structural characteristic of the synthetic zeolite produced (i.e. morphology, physico-chemical and phases identification) via XRF, SEM, FTIR, PXRD, TGA, BET and BJH and to evaluate the sorption capacity of the synthesized zeolitic material using aqueous solution of aromatic compoundsResearchers in science and engineering have increased interest in finding low-cost adsorbents such as industrial sludge waste, biomass, husk, slag, carbon slurry, bagasse fly ash (BFA), etc. to remove inorganic and organic pollutants from wastewater. There are many researcher results which were done on BFA for the removal of pesticide, dye, phenol etc but during survey of literature no research work is done on the removal of aniline, nitrobenzene and para nitroaniline using BFA and its derived zeolitic materials. Zeolites are aluminosilicates crystalline materials which contain pores and cavities of molecular dimensions. Many occur as natural minerals, but it is the synthetic varieties which are among the most widely used sorbents.
