Abstract:
In the present study the development of advanced nanomaterials that can be used as adsorbents for the treatment of pollutants. Due to rapid development of civilization together with the evolution of industry has caused deep changes in the quality of the environment in which the human beings live. The enhancing demands for a healthy environment, particularly for the removal of pollutants from industrial and municipal wastewater, are a major reason to search for new materials. So, there is an utter requirement to develop such advanced materials that have more adsorption sites for multiple pollutants because of their functionality along with high surface area. In present study, the major focus is to develop those advanced materials that can enhance the removal of variety pollutants from wastewater. Silica is natural precursor has tetrahedral structure. Due to its tetrahedral property, it has high inter porosity and greater binding sites. When it gets functionalized, it gives effective multi adsorptive site product that can be easily used as filter, as an adsorptive agent or can remove variety of pollutants of same sites from wastewater. Synthesis of silica bio-hybrids by using chitosan as natural organic moiety. Synthesized materials will be characterized by using SEM and EDX standard characterization techniques of FTIR to study the structure property relationship. The samples were analysed in the range of 400 to 4000cm-1 by FTIR spectrometer (Bruker Tensor 27 with Opus software). This work can be a positive addition to the development of advance materials. Batch adsorption studies were conducted for contaminants (phenol & dye) in order to examine the consequences of pH shifting, the adsorbent site availability and initial adsorbate concentration on adsorption and results were analysed by UV-VIS spectrophotometer. These synthesized products as adsorbents reported best removal of indigo carmine as compared to 4-nitrophenol from wastewater. These results are a positive contribution towards environmental remediation. Kinetic models are used to study adsorption process efficiency with respect to time. The applied isotherm and kinetic models suggested the physiochemical adsorption process. The intra-particle diffusion model expressed a three-phase adsorption mechanism including surface rapid adsorption, internal pores diffusion, and equilibrium
