Adsorption of hazardous dye Eosin Yellow from aqueous solution onto waste material De-oiled Soya: Isotherm, kinetics and bulk removal

► An adsorptive removal method for the eradication of Eosin Yellow from wastewater has been proposed. ► Eosine Yellow is a highly toxic dye and even possesses carcinogenic characteristics. ► During the studies preliminary investigations, isotherm measurements and kinetic studies have been done. ► The bulk removal of the dye has been made by employing glass column as a fixed bed adsorber. ► Attempts have also been made to recover the Eosine Yellow by eluting dilute NaOH solution through exhausted column.
