The present disclosure provides compositions, methods, and devices for sensing, detecting, and/or selectively capturing phosphate from water. An exemplary method includes: contacting a ligand or a rare earth metal complex of a ligand as described herein with an aqueous phosphate-containing medium at a pH of 5 to 12 under conditions sufficient to bind phosphate (e.g., reversibly bind phosphate). In certain embodiments, the method further includes releasing the bound phosphate by contacting the bound phosphate complex with an aqueous medium at a pH of 0 to 4 under conditions sufficient to release the bound phosphate.
本公开提供了用于感知、检测和/或选择性捕获水中磷酸盐的组合物、方法和装置。一种示例方法包括:将本文描述的配体或配体的稀土金属络合物与pH为5至12的含磷酸盐介质接触,在足以结合磷酸盐(例如,可逆结合磷酸盐)的条件下。在某些实施例中,该方法进一步包括通过将结合的磷酸盐络合物与pH为0至4的含水介质接触,在足以释放结合的磷酸盐的条件下释放结合的磷酸盐。
