ADSORPTION OF DYE RHODAMINE B BY IRAQI BENTONITE CLAY

Abstract

In this study, the adsorption of dye (Rhodamine B) by bentonite clay was investigated. Bentonite clay showed significant adsorption of this dye from aqueous solution.The langmuir and frendlish isotherm equations were applied to the data and values of parameters of these isotherm equations were evaluated. Kinetics study was made using lagergreen equation and a first order equation was obtained and the rate constant of adsorption was calculated.
