Synthesis of New Luminescent MOf and application as a sensor in detection of Cr(VI) Oxyanions

Mofs have attracted a lot of attention because of their extraordinary features, like Removal contaminants, fluorescence detection, gas storage and separation, drug delivery, chemical sensing, heterogeneous catalysis [1]. MOFs as a luminescent sensors responses towards small molecules, gas molecules, ions (cations and anions), pH, humidity, temperature, and biomolecules [2]. Cr(VI) is one of the cations that very dangerous for humans. especially for people working in the steel and textile industry. The effects of Cr(VI) on the human body These include stomach ulcers, skin inflammation, and skin sensitivities [3]. In this work we synthesized a new Cd Mof with a n donor Schiff base ligand and a carboxylic acid linker which have high selectivy for Cr(VI) Oxyanions in Aqueous Media. Also Compared to similar reports have a high Quenching constants (Ksv) .
