Study of Kinetic and Thermodynamic Parameters Related to the Adsorption of Azo Dyes Orange-G over Alum Modified Activated Carbon

Abstract

The study involves preparation of Aluminised activated carbon by treatment
of the carbon with(0.1M)Alum (KAl(SO4)2.12H2O). carbon prepared was used for the
removal of Orange-G dyes from aqueous solution . The study involved the adsorption
isotherm of the dyes over the aluminized carbon . The study assumes that the
adsorption of dyes over activated carbon is pseudo first order Investigation of the
effect of concentration, temperature, time and pH of the media was studied in detail to
choose the suitable condition for the kinetic and thermodynamic studies
