Equilibrium Studies and Kinetics Mechanism for the Removal of Congo red by Passiflora Foetida Activated Carbon–Mno2- Nano Composite
This paper presents the feasibility of removal of Basic dye (Congo Red) from aqueous solutions by using a low cost PAC-MnO2-NC. Batch adsorption experiments were carried out as a function of pH, contact time, initial concentration of the adsorbate, adsorbent dosage and temperature. Pseudo first order, Pseudo second order, intra-particle diffusion model and Elovich kinetic models were studied. Thermodynamic parameters such as ∆H ,̊ ∆S ̊, and ∆G ̊ were also calculated.
