Capture of pharmaceutical pollutants from water was studied using a novel fluorine-bearing covalent organic framework TpBD-(CF ) , which showed ibuprofen adsorption capacity of 119 mg g at neutral pH. This value is further enhanced at pH 2, highlighting the potential of this class of materials to serve as adsorbents even under harsh conditions. The adsorbed pharmaceutical can be recovered from TpBD-(CF ) in high yield, offering the option of recycling both the adsorbent and the pharmaceutical. The high efficiency of ibuprofen capture as compared to other less lipophilic pharmaceuticals suggests that COFs can be pre-designed for selective capture of contaminants.
使用新型含氟共价有机框架 TpBD-(CF ) 研究了水中药物污染物的捕获，该框架在中性 pH 下对布洛芬的吸附容量为 119mg·g 。在 pH 2 下，该值进一步提高，这突出表明此类材料即使在恶劣条件下也有作为吸附剂的潜力。吸附的药物可以从 TpBD-(CF ) 中以高产率回收，从而提供了回收吸附剂和药物的选择。与其他疏水性较低的药物相比，布洛芬的捕获效率很高，这表明 COFs 可以预先设计用于选择性捕获污染物。
