چکیده
Abstract In this study, iron oxide nanoparticles (Fe 3 O 4 ) and with humic acid coatings /HA) were investigated for the removal of U(VI). The effect contact time, adsorbent mass, U(VI) concentration, pH was studied by batch technique. sorption kinetic data follows pseudo-second order, while isotherms obey Langmuir Q max values 238.0, 195.6 mg/g Fe /HA, respectively. According to decreases capacity magnetite due formation a polyanionic organic coating, altering surface properties particles, reducing aggregation, stabilizing suspension.

The performance of olive stone activated carbon (OSAC) for sorption of Cu2+, Zn2+ and Ni2+ ions was investigated via batch technique. OSAC materials were prepared under different physially activation conditions. Olive stone waste was physically activated with N2 gas and steam gas at 900oC at 3.5h hold time (OSAC-3) was choice as the best one for Cu2+, Zn2+ and Ni2+ removal. Characterization for...
