Regenerable, high‐efficiency salt sorption materials are highly desirable for water treatment. Here, a thermoresponsive, amphoteric metal–organic framework (MOF) material is reported that can adsorb multiple salts from saline water at room temperature and effectively release the adsorbed salts into water at elevated temperature (e.g., 80 °C). The amphoteric MOF, integrated with both cation‐binding carboxylic groups and anion‐binding tertiary amine groups, is synthesized by introducing a polymer with tertiary amine groups into the cavities of a water‐stable MOF such as MIL‐121 with carboxylic groups inside its frameworks. The amphoterized MIL‐121 exhibits excellent salt adsorption properties, showing stable adsorption–desorption cycling performances and high LiCl, NaCl, MgCl2, and CaCl2 adsorption capacities of 0.56, 0.92, 0.25, and 0.39 mmol g−1, respectively. This work provides a novel, effective strategy for synthesizing new‐generation, environmental‐friendly, and responsive salt adsorption materials for efficient water desalination and purification.

用于高效可逆吸附水中多种盐的热响应性两性金属有机框架
可再生、高效的盐吸附材料对于水处理来说是非常理想的。据报道，一种热响应性两性金属有机骨架（MOF）材料可以在室温下从盐水中吸附多种盐，并在高温（例如80℃）下有效地将吸附的盐释放到水中。通过将具有叔胺基团的聚合物引入框架内具有羧基的水稳定 MOF（例如 MIL-121）的空腔中，合成了兼有阳离子结合羧基和阴离子结合叔胺基团的两性 MOF。 。两性化的MIL-121表现出优异的盐吸附性能，表现出稳定的吸附-解吸循环性能和高LiCl、NaCl、MgCl 2和CaCl 2吸附容量，分别为0.56、0.92、0.25和0.39 mmol g -1 。这项工作为合成新一代、环境友好、响应性盐吸附材料以实现高效的水淡化和净化提供了一种新颖、有效的策略。
