Abstract
This study represents a novel application for the removal of heavy metals from industrial waste effluent with the help of Biomass Ash and Guar-Gum nanocomposites. Researches have been shown that biomass use instead of fossil fuels for energy conversion. Biomass sample may also include herbaceous and agricultural residues like rice husks, wheat straw, wood, sunflower shells etc. Properties of biomass like heating value, moisture content, ash content, susceptibility to slagging and fouling and volatile content makes it a good fuel and appropriate modification of biomass ash with chitosan nanocomposite have been shown to effectively remove heavy metals from industrial wastewater. Guar gum nanocomposite will be used to adsorb heavy metal from the waste water stream .Due to its thickening, emulsifying, binding and gelling properties, quick solubility in cold water, wide pH stability, film forming ability it can be used as an adsorbent in the adsorption process. Guar gum is the powdered endosperm of the seeds of the Cyamopsis tetragonolobus which is a leguminous crop. The endosperm contains a complex polysaccharide called galactomannan, which is a polymer of d-galactose and d-mannose. Characterization of nanocomposite by using TGA, XRD, TEM ,SEM ,FTIR shows the better possibility as chemical adsorbents for entrapping metals ions present in waste water.
