The adsorption of Methyl violet and Congo red from aqueous solution onto untreated and hexadecyltrimethylammonumbromide (HTAB) treated adsorbent and have been studied using an agitated batch adsorber. The influences of contact time, initial dye concentration, pH, and adsorbent mass have been studied. The parameters of Langmuir, Freundlich adsorption isotherms and kinetics parameters have been determined using the adsorption data.
