Evaluation of the Adsorption Kinetics andEquilibrium for the Potential Removal of Congo RedDye From Aqueous Medium by Using a Biosorbent

摘要

Activated Mangifera indica Saw Dust (AMSD) has been investigated as low cost and eco-friendly biosorbent prepared for the removal of Congo red (CR) in aqueous solution. Various adsorption parameters such as effect of contact time, adsorbent dose, effect of pH and initial concentration of Congo red on the adsorption capacity of the adsorbent were studied. The adsorbent was also characterized by FTIR, XRD and SEM Analysis. The equilibrium data followed both Langmuir and freundlich isotherm. The kinetic parameters of adsorption such as Lagergren Pseudo first order, Pseudo second order have also been studied. These studies suggest that the AMSD Could be used as a low cost alternative for waste water treatment for dye removal.
