Fly as., obtained from a thermal power plant, Anpara, s.nebhadra, India has.been us.d as.an effective ad-s.rbent for the removal of malathion from aqueous.s.lutions. The time required to attain equilibrium was.found to increas. from 40 to 60 minutes.as.the initial malathion concentration increas.s.from 1 to 10 mg/L. The optimum pH value for ads.rption was.4.50. The removal of malathion increas.d by increas.ng the tem-perature indicating endothermic nature of removal proces.. The fly as. exhibited firs. order rate kinetics.and followed both Langmuir and Freundlich is.therm models. Endothermic nature of ads.rption proces. was.further s.pported from increas.ng values.of Langmuir and Freundlich cons.ants.with increas. in temperature. The ads.rbent can be us.d as.an economical product for the removal of malathion from was.ewater als.. A comparis.n of the ads.rption capacity of fly as. with other ads.rbents.s.ows.that fly as. can be us.d for the removal of malathion from aqueous.s.lutions.
