… much more Pb2+ ions than kaolinite. The difference is largely due to the surface charges
on the clay minerals. Removal of Pb2+ ions from variable-charge minerals (eg, kaolinite) …

… + and Cd2+ decreased the adsorption capacity of Unmodified Kaolinite clay for Pb2+ by …
of the both metal ions from the Unmodified and PVA-modified kaolinite adsorbents. Prior to …

… by TPP-Kaolinite clay and increased that for Cd 2+ . The adsorption capacity of TPP-Kaolinite
clay for both metal ions was also decreased by simultaneous presence of both metal ions. …

… kaolinite clay and the mechanism of lead ion adsorption on both phosphate-modified and
unmodified kaolinite clay … phosphate-modified and unmodified kaolinite clay. These studies are …

… In addition, Pb 2+ mixed with other ions and confined within mixed clays has not been given
sufficient attention. Based on this, two questions have arisen: (1) Does the invasion of Pb 2+ …

… Exposed hydroxyl groups along the alumina faces of kaolinite may also be able to exchange
H + ions for some cations. The total alumina facial charges are greater when fewer kaolinite …
