A colored substance (B) is to be removed from a mineral oil by adsorption with clay particles at 25oC. The original oil has a color index of 200 units/l00 kg oil, while the decolorized oil must have an index of only 20 units1100 kg oil. The following experimental adsorption equilibrium data have been measured in a laboratory: Cn, color units/ 100 kg oil 100 40 200 10 60 10 (a) Fit the data to the Freundlich equation.(b) Compute the kilograms of clay needed to treat 500 kg of oil if one equilibrium contact isused.
