Kinetics And Isotherm Studies On Cationic Dyes Adsorption Onto Annona Squmosa Seed Activated Carbon
نویسنده
چکیده
The use of low cost, locally available and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. This study investigates the potential use of activated carbon prepared from the Annona squmosa seed for the removal of methylene blue (MB) , methyl red (MR) and malachite green (MG) dyes from simulated wastewater. Adsorption of MB, MR and MG dyes on the Annona squmosa seed showed highest values at around pH 7.0, and followed second –order kinetic with intraparticle diffusion as one of the rate determining steps. The adsorption-equilibrium was represented with Langmuir, Freundlich, Dubinin-Radushekevich and Tempkin isotherms. Activated carbon developed from the Annona squmosa seed can be an attractive option for dyes removal from diluted industrial effluents.
