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.

取决于面的Cu ₂ O珠被用作一种有前途的吸附剂，用于还原U（VI）并从水溶液中分离。Cu ₂ O珠表现出438.93 mg·g ^-1的潜在还原吸附能力。此外，这种新型吸附剂的吸附性能与Freundlich等温线和拟一级动力学模型非常吻合。说明了还原吸附过程中Cu ₂ O中小面的影响。与立方和多面Cu ₂ O珠相比，八面Cu ₂ O表现出色。鉴于吸附剂的优势，例如U（VI）的高去除性能，使用方便和对环境友好的Cu ₂O珠将是放射性U（VI）环境修复的杰出候选者。
