Abstract


In this paper, we addressed the issue of using organo-K10 montmorillonite as adsorbent of DS to remove it from aqueous environment. An organo-K10 montmorillonite (MK10-C16) was prepared by intercalating the organic cation cetyltrimethylammonium bromide (C16) in a K10 montmorillonite (MK10), than characterized using XRD analytical technique. The organo-K10 montmorillonite displayed enhanced affinity for the DS in water. Using a linear regression, the pseudo-second-order model describes better the results of the kinetics. The adsorption data fitted well with Langmuir isotherm. The maximum adsorption capacity of diclofenac is estimated to be 63.33 mgg-1. The results revealed that MK10-C16 have a high potential to be used as adsorbent for the removal of DS from aqueous solution.
