Reference work entry


Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. In this study, we developed an effective adsorbent for retention of Co(II), Ni(II), Cu(II), and Zn (II) by modifying kaolin clay with an amino-terminated organosilicon (3-aminopropyltriethoxysilane, APTES). The lamellar filler (original clay) used is the kaolin (K08) from Bechar–Algeria region. Characterization of modified clay material and original clay was carried out by different methods XRD, FTIR, TGA, and SEM to establish the link between syntheses, structures, and properties. The adsorption of heavy metal ions onto APTES-modified kaolin showed greater efficiency than original kaolin. These results indicate that the APTES-modified kaolin may be used as very effective adsorbent for removal of heavy metals from aqueous media.
