An Ultra-stable Eu3+ Doped Yttrium Coordination Polymer with Dual-function Sensing for Cr(Ⅵ)and Fe(Ⅲ)Ions in Aqueous Solution
文献摘要：
The exploration of a dual-functional sensor is the key to effectively detect the Cr(Ⅵ)and Fe(Ⅲ)cations in water,which is important to human health and environmental sus-tainability.Because of the phase stability and excellent luminescence,the rare-earth coordina-tion polymers have great potential as dual-functional sensors.Here,we develop a Y0.91Eu0.09(H2O)2{C6H3(CO2)3}(MIL-92(Y):9％Eu3+)-based dual-function luminescent sensor on Cr(Ⅵ)and Fe(Ⅲ),which exhibits excellent phase stability and dispersibility in water.The lumi-nescence of MIL-92(Y):9％Eu3+aqueous suspension quenches on Fe3+with Stern-Volmer con-stant Ksv of 1.79×103 M-1 and limit of detection of 17 μM.The MIL-92(Y):9％Eu3+aqueous suspension also has turn-off sensing ability towards Cr2O72-and CrO42-with Ksv values of 3.5×103 and 6.14×103 M-1,respectively.It has detection limitations of 10 and 5 μM on Cr2O72-and Cr2O72-ions,respectively.
