Determination of Parameters in Fixed Bed with Industrial Waste Used as Adsorbent

Determination of Parameters in Fixed Bed with Industrial Waste Used as Adsorbent

In this study, adsorption studies of aqueous solution of malachite green dye in fixed bed using fly ash were carried out . The effect of adsorbent amount was investigated. Thomas, Adams-Bohart and Yoon-Nelson models were used to evaluate the results obtained. In addition, the correlation between the model and the experimental data was compared using seven non-linear nonlinear functions, while the adsorption dynamics of the fixed bed column were modeled.
