Kinetic and thermodynamic study of the adsorption of methylene blue over magnetic activated carbon

Abstract EN

The study involves preparation of magnetic activated carbon by treatment of the carbon with(0.25M) Fe2(SO4)3.5H2O Carbon prepared was used for the removal of methylene blue dyes from aqueous solution.

The study involved calculation of heat of adsorption of the dyes over the magnetic carbon.

The study assumes that the adsorption of dyes over activated carbon is pseudo second order.

Investigation of the effects of concentration, temperature, time and pH of the media were studied in detail to choose the suitable conditions for the kinetic and thermodynamic studies.
