Kaolin, cationic dye, acid activation, polyvinyl alcohol, isotherms


In this study, the adsorption of Brilliant Blue G-250 (BBG), cationic dye onto Kaolin and modified – kaolin samples was investigated. Kaolin was used as a raw material to prepare three different adsorbents through chemical modification by using nitric acid, polyvinyl alcohol and a mixture of polyvinyl alcohol with nitric acid. Characterization studies were performed using XRD, FTIR, SEM, BET surface area and pore structure. Batch adsorption studies were carried out to evaluate the effect of adsorbent dose (0.1 – 0.4g), initial dye concentration (50 -250 mg/L) and temperature (298 – 333K) on the adsorption capacity of BBG dye. The experimental equilibrium adsorption data was represented using two – parameter isotherm models including Langmuir, Freundlich, Elovich, Temkin, Halsey, Harkin – Jura and Flory – Huggin isotherms. Adsorption isothermal data satisfactorily fits with the Langmuir model and the maximum adsorption capacity was found to be 50mg/g for the kaolin sample modified with nitric acid. Thermodynamic studies showed that the dye adsorption is exothermic and a spontaneous process. These results indicate that modification of kaolin could be promising as a cheap adsorbent for the removal of BBG dye from aqueous solutions.
