-
Fe-rich sludge is converted into nano-flake Fe-SC-800 by carbothermal process.
-
Fe-SC-800 has favorable ability for immobilization of uranium.
-
Langmuir model fitted well with the isotherm adsorption of Fe-SC-800 to uranium.
-
Pseudo-second order model fitted well with the adsorption kinetic of Fe-SC-800 to uranium.
-
Reductive and physical adsorptions are contributed to the preferable immobilization mechanisms.
