Studies on the removal of dyes from Waste water by activated carbon Developed from agricultural waste Activated with sulphuric acid

Abstract

A greenhouse gas emitting agricultural waste is activated to form an activated newlinecarbonn and it is tested for its efficiency by the adsorption studies Various dye newlinesolutions of Methylene Blue MB Crystal Violet CV Malachite Green MG and newlineBismarck Brown Y BBY from the dye house waste waters are tested for its newlineefficiency mechanism of adsorption with this activated carbon The BET surface area newlineanalysis SEM EDAX FTIR and XRD studies are carried out to know morphology of newlineactivated carbon newlineThe Batch mode of experiments has been carried out for adsorption studies the newlineAreca Husk Carbon AHC The limiting factors of the adsorption of dye have been newlinerevealed by the particle size adsorbent dosage initial dye concentration contact time newlinepH and temperature The Pseudofirst order Intra particle diffusion Banghamns and newlineBoyd kinetic models has been attempted in order to infer the feasibility of the research newlineon adsorption The data obtained in these studies are based upon the differential initial newlinedye concentrations newline newline
