The natural clay bentonite (B) as adsorbent of lead cations was studied. To enhance its adsorption capacity, the coating by iron oxide particles, in two selected weight ratios: 2:1 (BM1) and 4:1(BM2), was used. The changes of the textural and surface parameters after the modification were studied by the low temperature nitrogen adsorption, XRD and ...
