This study used kelp to create biochar (BC) and then modified it with iron-doped zinc oxide (nFe-ZnO) to prepare Fe-ZnO@BC. Under optimal conditions, the adsorption capacity of Fe-ZnO@BC for U(VI) was 146.16 mg g-1. Freundlich isotherm and quasi-second order kinetic model exhibited excellent fitting to the isotherm and kinetics of uranium adsorption by Fe-ZnO@BC, respectively. The thermodynamic analysis indicated that the U(VI) adsorption process was endothermic and spontaneous. After six adsorption cycles, Fe-ZnO@BC retained its remarkable U(VI) removal performance. Advanced characterization ...
