The aim of this study is to use Activated charcoal prepared from wood apple shell (Limonia acidissima L.) by chemical and microwave activation method as an adsorbent for the removal of methylene blue (MB) dye. The kinetics and equilibrium adsorption of methylene blue dye on this adsorbent were then examined at 299.4K. The adsorption isotherm of the methylene blue on the adsorbent was determined and correlated with common Langmuir and Freundlich adsorption isotherm equations. The Langmuir isotherm exhibited a better fit for the adsorption data than the Freundlich isotherm with maximum monolayer adsorption capacity of 48.31 mg g-1. The kinetics of methylene blue adsorption on the treated adsorbent has also been studied by fitting the data in various kinetic models. It was observed that the removal of methylene blue over the activated adsorbent undergoes the pseudo-second order kinetic. The kinetic parameters of this best-fit model were calculated and discussed.
