Recently, the pollution and damage caused by antibiotics in water have aroused serious concerns. In this situation, it is extremely important to develop a highly effective approach to detect antibiotics in water. In this contribution, we built a Cd-MOF material with stable fluorescence properties, using bbi = 1,4-bis(2-methyl-imidazol-1-yl)butane and H2L = 1,2-phenylenediacetic acid as organic ligands and Cd(NO3)2·4H2O as the metal node. The highly selective response of this MOF probe to ceftriaxone sodium (an antibiotic) can reach up to the ppb level in water, along with a fast response time, acid and alkali resistance, and anti-interference ability.
最近，抗生素在水中造成的污染和破坏引起了人们的严重关注。在这种情况下，开发一种高效的水中抗生素检测方法极为重要。在本研究中，我们使用bbi=1,4-双(2-甲基-咪唑-1-基)丁烷和 H2L=1,2-苯二乙酸作为有机配体，以 Cd(NO3)2·4H2O 作为金属节点，构建了一种具有稳定荧光性质的 Cd-MOF 材料。该 MOF 探针对头孢曲松钠（一种抗生素）具有高度选择性的响应，在水中的检测下限可达 ppb 级，并且具有快速的响应时间、耐酸碱和抗干扰能力。
