Experimental Study of Removal of Rhodamine B by an Activated Cereal by Product

AbstractDyes have been used in dyeing paper and pulp, textiles, plastics, leather, cosmetics and food industries. Colour stuff discharged from these industries poses certain hazards and environmental problems. In this work we study the potential feasibility of treated and untreated cereal by product for removal of Rhodamine b from aqueous solution. The effect of various experimental parameters such as contact time and initial concentration were investigated. The suitability of the Freundlich, langmuir, BET and Hrkin Jura models to the equilibrium data was investigated for Rhodamina b-CCBP system. The results showed that the equilibrium data fitted the freundlich model best. Kinetic modeling of removal of Rhodamine B was done using the pseudo second-order rate expression
