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测、检测和/或选择性捕获水中磷酸盐的组合物、方法和装置。一种示例性方法包括:在足以结合磷酸盐(如可逆结合磷酸盐)的条件下,将本文所述的配体或配体的稀土金属络合物与 pH 值为 5 至 12 的含水磷酸盐介质接触。在某些实施方案中,该方法还包括在足以释放结合的磷酸盐的条件下,将结合的磷酸盐络合物与 pH 值为 0 至 4 的含水介质接触,从而释放结合的磷酸盐。
