Synthesis and characterization of Polyamides and polyesters for removal of Heavy metal ions from aqueous solution

Abstract

Life on planet earth depends on various natural resources and one newlinesuch major resource is water Water pollution is a major environmental issue newlinefaced by the modern world which leads to ecological disequilibrium which newlinecan cause harmful effect on flora and fauna of the ecosystem Pollution of newlinewater by heavy metals beyond a permissible limit is considered a threat due to newlinetheir immense toxicity and their non biodegradability The purpose of newlinewastewater treatment is to remediate polluted water and to reuse it within newlineacceptable quality standards Adsorption is a promising method for the newlineremoval of metal ions from wastewater because of its high efficiency ease of newlinehandling and abundant availability of different classes of adsorbents In the newlinepast few years polymeric adsorbents have been emerging as a potential newlinealternative to other adsorbents in terms of their vast surface area perfect newlinemechanical rigidity adjustable surface chemistry pore size distribution newlineselectivity towards heavy metal ions and feasible regeneration newline newline
