A Compa rative Stu dy for Re moval of Alizarin Red S from Aqueous Sam ples by M agnetic N anoparti cles of Fe۳O۴, CoFe۲O۴ and Fe ۳O۴ by Us ing Ionic Liquid as M odifier

Dye a nd dye stuffs are extensively used in various areas su ch as textile, plastic, food, cosmetic, carpet and paper ind ustries. Wastewaters of these industries contain dye with m etals, salts, and other ch emicals which may be toxic to aquatic environment. Hence, the presen ce of dyes in wastewaters is a m ajor environ mental problem as th ey are generally resista nt to degra dation by biological treatment meth ods. Many investigations have be en reported using differe nt methods for the re moval of dyes from water and wa stewater including biol ogical proces ses, combi ned chemical and biochemical pro cesses, chemical oxid ation, adsorption, coagulation, and membrane treatments. S everal articl es have been published on the appli cation of various nanop articles for the treatmen t and remediation of pollutants in the environ ment [۱-۳].This work focuses on compa rative study for the re moval of Fe ۳O۴, CoFe۲O۴ and IL- Fe۳O۴ nanoparticles as adsorbents f or adsorption of alizarin red S. Ads orption isotherms, kinetic of adsorp tion and the rmodynamic parameters were chara cterized.
