Evaluation of dynamics and equilibrium models for the sorption of Basic Violet 3 on activated carbon prepared from Moringa Oleifera fruit shell waste
Journal Title: Carbon - Science and Technology - Year 2014, Vol 6, Issue 1
Abstract
The feasibility of activated carbon prepared from Moringa oleifera fruit shell waste to remove Basic Violet 3 from aqueous solution was investigated through batch mode contact time studies. The surface chemistry of activated carbon is studied using Boehm titrations and pH of PZC measurements indicates that the surface oxygenated groups are mainly basic in nature. The surface area of the activated carbon is determined using BET method. The kinetics of Basic Violet 3 adsorption are observed to be pH dependent. The experimental data can be explained by Pseudo second order kinetic model. For, Basic Violet 3, the Langmuir model is best suited to stimulate the adsorption isotherms.
