Kinetic Studies of Colour and Phenol Removal from Wastewater using Mango Seed Shell Activated Carbon

Abstract

Kinetic studies by batch technique were carried out using activated carbon prepared from mango seed shell for the adsorption of colour and phenol from wastewater. The data generated from the studies were used for kinetic modelling in order to determine the rate and mechanism of adsorption. The results revealed that adsorption was best fitted by the pseudo-second order model for both methylene blue (MB) and phenol adsorptions. Intra-particle diffusion kinetic plots did not pass through the origin, indicating that intra-particle diffusion was not the only rate controlling mechanism. The results showed that mango seed shell activated carbon (MSSAC) is more effective for adsorption of colour than phenol in wastewater.
