Cover Story: The adsorption of ketoprofen, naproxen, and diclofenac on halloysite/carbon nanocomposites and non-modified halloysite were studied. Halloysite/carbon nanocomposites were obtained through liquid phase impregnation and carbonization using saccharose as the carbon precursor. Adsorption ability of halloysite/carbon nanocomposites was much higher for all the studied adsorbates in comparison to non-modified halloysite. Optimized chemical structures of ketoprofen, naproxen, and diclofenac obtained by DFT calculation showed that charge distributions of these adsorbate molecules and their ions can be helpful to explain the details of adsorption mechanism. Halloysite as a nano-carrier combined with carbon may be a probable suitable adsorbent of all the studied pharmaceuticals for large scale application. View this paper.
