A Cd-MOF Sensor for Fluorescence Detection of Al3+
The content of aluminum ions in water will directly affect the ecological environment and ecological balance in water bodies.As the third most abundant element in the earth's crust,aluminum is widely used in daily life.However,excessive intake of Al3+can lead to various diseases,such as Parkinson's disease,Alzheimer's disease,dementia and so on.Furthermore,high concentrations of Al3+have been shown to be at high risk for ecological environments.Therefore,detecting Al3+in environmental samples is a crucial hot issue.In this paper,a 3D Cd-MOF fluorescent probe was synthesized by hydrothermal method using cadmium metal ions and 3-(3,4-dicarboxyphenyl)isonicotinic acid to detect Al3+in aqueous solution with the detection limit of 2.62 μmol·L-1,it showed good sensitivity,high selectivity and recyclability.Overall,this Cd-MOF has broad applications and development prospects as a fluorescence detection material.
