Kinetic Studies of Adsorption of Chrome Blue-Black by Modified Peanut Husk

Abstract:

Modified peanut husk was used as an adsorbent to remove chrome blue-black from its aqueous solution. Results of kinetic experiments demonstrated that the adsorption was effective and rapid.Three different kinetic models (i.e.,intraparticular diffusion model, Lagergren-first-order and second-order equations) were used to describe the adsorption mechanisms. The adsorption of chrome blue-black on modified peanut husk was not controlled by intraparticular diffusion. The kinetic adsorption data can be well simulated by the second-order equation and the adsorption might be rate-limiting controlled. The suitability of the adsorbent was tested by fitting the equilibrium data with Langmuir and Freundlich isotherms, which gave good fits with both isotherms.
