Studies on Industrial Effluent Pollutant Removal by Noval Unsaturated Polyester Glycerol Maleic Anhydride Resacetophenone Agriculture Waste Mixture

Abstract

The polymers are important materials today. They are classified as thermoplasts and thermosets. The thermoplasts are mostly vinyl type i.e. polyethylene, polypropylene, polystyrene, polyvinyl chloride etc. The thermosets are phenolics urea-formaldehyde resin, maleimine-formaldehyde resin, epoxy resin, unsaturated polyester etc. More particularly the unsaturated polyester (USPE) play the pivotal role in many versatile applications. Today commodity application of USPE are: Switch board, steam boat, fibre reinforced roofs, paints. Some area like water pollutant adsorbants from USPE has not been developed. newline[-OOC-CH-CH-COO-R]-OH newline(USPE)Where, R=Alkyl newline The pollution of water and soil with metal cations has increased dramatically in the last 50 years as a consequence of the expedition of industrial activities. The well established toxicity of metals in solution at sufficiently high concentrations affects humans, animals and vegetation. Due to the problems mentioned, attention has been focused on the various adsorbents, which have metal binding capacities and are able to remove unwanted heavy metals from contaminated water at low-costs. Because of their low cost and local availability, natural materials such as chitosan, zeolites, clays, or certain waste products from industrial operations such as fly ash, coal and oxides are classified as low-cost adsorbents. A suitable adsorbent for adsorption processes of pollutants should meet several requirements : newline(i) efficient for removal of a wide variety of target pollutants; newline(ii) high capacity and rate of adsorption; newline(iii) important selectivity for different concentrations; newline(iv) granular type with good surface area; newline(v) high physical strength; newline(vi) able to be regenerated if required; newline(vii) tolerant for a wide range of wastewater parameters; and newline(viii) low-cost. newline The area in which the modification of USPE towards the pollutant adsorbents has not been developed academically and technically.
