Micelle-Clay Adsorption Efficiency towards the Removal of Cr(VI) from Aqueous Solutions

The elimination efficiency in aqueous solutions of either clay (montmorillonite) or micelle-clay complex towards Cr(VI) was investigated. From the adsorption of critical micelle concentration of octadecyltrimethylammonium ions onto clay, the micelle-clay complex was prepared. To investigate the effects of pH, contact time and adsorbent dosage on the removal efficiency of Cr(VI) from aqueous solutions, batch experiments were performed. The experimental results were found to significantly fit the Langmuir adsorption isotherm. In order to test the Cr(VI) removal efficiency under continuous flow at various pH values, columns charged with a mixture of micelle-clay complex and sand were used. The results showed that without any previous acidification of the sample, the micelle-clay complex used in this study was able to extract Cr(VI) from aqueous solutions. In addition, they revealed that when optimum conditions for both batch and continuous flow techniques were used, the removal effectiveness of the complex was around 100 percent.
