Abstract
Here firstly report a novel 3D bimetallic MOF. It can be used as a fast ratiometric fluorescent probe and fast adsorbent for Pb2+ ions with its greatly fluorescence enhancement and a large red-shift stokes of 166 nm, which is the biggest shift of references. Moreover, it is also the first reported MOF material that can quantitatively analyze the lanthanide metal element Tb3+ among LMOFs. The limits of detection are calculated as 4.12 × 10−6 M and 2.94 × 10−5 M. ICP-OES testing and calculation showed that the maximum adsorption capacity of LMOF-1 for Pb2+ was calculated to be 23.75 mg/g at five minutes.
期刊介绍：
The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field.
Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
