Adsorption of Malachite Green Using Activated Carbon From Copper Pod
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 8
Abstract
In the present study, the adsorption capacity of waste materials of copper pod fruit was determined for the removal of malachite green dye from aqueous solutions. This batch adsorption experiment was carried out to study for the various parameters such as adsorbent dosage, contact time, initial metal ion concentration, pH value and temperature. The morphology was investigated by scanning electron microscope and X-Ray diffraction data. The equilibrium data in aqueous solution were analysed using Freundlich, Langmuir isotherm model, Tempkin and Dubinin - Radushkevich isotherm. Adsorption isotherm of malachite green dye obeyed Langmuir isotherm model, Tempkin and Dubinin - Radushkevich isotherm. The kinetic data in aqueous solution were studied using Pseudo-first and Pseudo-second order kinetic models, Intraparticle diffusion and Elovich model. It was found that the adsorption of malachite green onto copper pod fruit activated carbon (CPFAC) followed pseudo second order kinetic model and Elovich model. The high values of correlation coefficient (R2 ) of intraparticle diffusion model indicated that the pore diffusion plays a significant role for the adsorption.The results indicate that the activated carbon prepared from copper pod fruit could be employed as a low-cost alternative to commercial activated carbon for the elimination of malachite green from waste water and aqueous solutions.
