Amino‐Fortified AIEgens Functionalized SBA‐15 for Detecting Environmental Contaminants Furazolidone and Potassium Dichromate

ABSTRACT Aggregation‐induced emission fluorogens (AIEgens) functionalized mesoporous silica SBA‐15 was synthesized through the simple post‐grafting method, then abundant amino groups were modified via a soaking and evaporation process in order to enhance the material's fluorescence intensity. The prepared fluorescent sensor AFSBA15 emitted strong blue light centered at 490 nm, and could detect furazolidone and potassium dichromate with low LOD values as 1.08 and 3.65 µM, respectively. What's more, AFSBA15 could selectively detect furazolidone and potassium dichromate without disturbed by other pollutants such as phenol, glyphosate, chlorfluazone, AlCl 3 , PbCl 2 , CuCl 2 ·2H 2 O, KOH, KCl, K 2 CO 3 , and K 2 SO 4 , exhibiting potential application in water quality monitoring and pollutant treatment.
