Natural <i>versus</i> organophilized smectites as drug adsorbents: experiment and molecular modeling.

ABSTRACT: To adsorb pollutants from water, smectites are commonly modified with quaternary ammonium compounds. However, these are also environmentally hazardous. This study aims to highlight that original smectites can compete with modified ones and that modification is not necessary. Original smectites - montmorillonite (MMT), beidellite (BEI), nontronite (NON) - and the same smectites modified with tetradecyltrimethylammonium (TTA⁺), denoted as MMT-M, BEI-M, NON-M, were studied as adsorbents of drugs ampicillin (AMP) and lamotrigine (LAM). Adsorbents before and after adsorption were studied using Fourier-transform infrared spectroscopy, elemental analysis, X-ray powder diffraction, thermogravimetry, and molecular modeling. The adsorption efficiency of original smectites reaches or excee
