  ABSTRACT: Arsenic (III) adsorption has been studied as a function of concentration of arsenic (III) in the solution, pH of the solu- tion, contact time during the batch extraction process using montmorillonite (MMT) and surfactant modified MMT (CPC-MMT and CTAB-MMT) from aqueous solution It has been observed that up to 90% of arsenic (III) can be ex- tracted from a solution containing 100 ppm of As (III) at pH 8.0, within a contact time of 10 minutes. The lowest level of As (III) that could be extracted was found to be 0.4 ppm.
