AB Selective and sensitive solid sensory substrates for detecting Al(III) in purewater are reported. The material is a flexible polymer film that can be handled and exhibits gelbehavior and membrane performance. The film features a chemically anchored salicylaldehydebenzoylhydrazone derivative as an aluminum ion fluorescence sensor. A novel procedure formeasuring Al(III) at the ppb level using a single solution drop in 20 min was developed. In thisprocedure, a drop was allowed to enter the hydrophilic material for 15 min before a 5 mindrying period. The process forced the Al(III) to interact with the sensory motifs within themembrane before measuring the fluorescence of the system. The limit of detection of Al(III)was 22 ppm. Furthermore, a water-soluble sensory polymer containing the same sensorymotifs was developed with a limit of detection of Al(III) of 1.5 ppb, which was significantlylower than the Environmental Protection Agency recommendations for drinking water.
