BENTONITE/IRON OXIDE MAGNETIC COMPOSITES: CHARACTERIZATION AND APPLICATION AS Pb(II) ADSORBENTS
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 ...
