Adsorption method has been developed for the removal of Rose Bengal, a highly toxic fluorescien class of dye from wastewater. The dye is highly toxic halogen containing dye whose touch can cause skin and eye irritation to human being. Waste material De–Oiled Soya, an agriculture waste product was successfully utilized in removing Rose Bengal dye. Under batch technique effect of pH decreases with increase the pH, although increase in concentration, temperature, amount of adsorbent and sieve size increased the adsorption of dye onto adsorbent material. The continuous flow system in the column adsorption shows an effective and encouraging result in adsorption and desorption on dye. Various parameters such as fractional capacity of the column, mass flow rate, percentage saturation of column etc. were calculated. The percentage saturation was found to be 98.97%. The recovery of the dye was made by eluting dilute NaOH through exhausted columns and almost 90.93% recovery of the dye was achieved for De–Oiled Soya column.
