摘要
The effective capture and storage of the generated radioactive contaminant (iodine) are of great significance with the extensive use of nuclear energy. In this work, a novel Cu nanoporous aerogel (Cu-NPA) was prepared by using inorganic Cu salt as precursors. The as-prepared Cu-NPA was fully characterized in detail, and the I2 adsorption and stability capability of Cu-NPA has been investigated in the solution. The results showed that Cu-NPA has high specific surface area and porosity. The structure of hierarchical pores is conducive to the rapid enrichment of pollutants in water. Adsorption experiments showed that Cu-NPA had ultra-high I2 adsorption capacity (1384 mg/g) and fast equilibrium adsorption time (10 min). The I2 in the solution (c < 1200 mg/g) can be almost completely removed. In addition, Cu-NPA exhibits good stability in the air and can be exposed to air for a long time. In general, our work demonstrated the preparation of Cu-NPA and its great potential in the field of rapidly eliminating radioactive I2.
