Abstract The facet-dependent Cu2O beads were employed as a kind of promising adsorbent for U(VI) reduction adsorption and separation from aqueous solutions. Cu2O beads exhibited potential reduction adsorption capability of 438.93 mg g−1. Furthermore, the sorption performance of this novel adsorbent agreed well with the Freundlich isotherm and pseudo-first-order kinetic model. The influences of facets in Cu2O were illustrated during reduction adsorption. Octahedral Cu2O performed excellently compared with the cubic and polyhedral Cu2O beads. Given the advantages of the adsorbent such as high removal behaviors of U(VI), convenience of use and enviromentally-friendly, Cu2O beads would be an outstanding candidate for radioactive U(VI) environmental remediation.
