Cucurbit[6]uril (Q[6]) could serve as a selective absorbent for the toxic anion Cr₂O₇²⁻, which was demonstrated by the results of UV-vis, ICP, XPS, SEM, and EDS experiments. Single-crystal X-ray diffraction analysis revealed that capture capacity could be attributed to the outer-surface interactions of cucurbit[n]uril between Cr₂O₇²⁻ and the outer surface of Q[6].

葫芦[6]脲无孔纯晶体选择性去除水溶液中的 Cr2O72−

UV-vis、ICP、XPS、SEM 和 EDS 实验结果证明，Cucurbit[6]uril (Q[6]) 可以作为有毒阴离子 Cr ₂ O ₇ ²⁻的选择性吸收剂。单晶X射线衍射分析表明，捕获能力可归因于Cr ₂ O ₇ ²⁻和Q[6]外表面之间葫芦[ n ]uril的外表面相互作用。
