Abstract

A new generation of grains based on an iron organo-inorgano montmorillonite complex and gluten (G) as an inert bonding agent called Fe-COIMG and were prepared by the dry compression granulation method. Their efficiencies were evaluated in tests for the removal of Malachite green cationic dye (MG) by adsorption in fixed bed columns. The effects of dynamic adsorption parameters such as bed depth, initial concentration and inlet flow rate were investigated. The breakthrough curves were exploited by the Thomas and Yoon and Nelson models using nonlinear regression. The corresponding results showed a good agreement with the experimental results obtained indicating that the model predictions were appropriate for the design of the column.
