The limit of detection for Al3+ ions of this synthesized probe was found to be 9.29 x 10(-7) M, while the Ka constant value was determined to be 1.64 x 10(4) M-1. The stoichiometric binding ratio of L-Al3+ was found to be 2:1 using the Job's plot method, and this ratio was also confirmed by H-1-NMR titration and mass spectrometry. The recyclability of the chemosensor was found by the fluorescence method through the addition of EDTA to the L-Al3+ solution. The obtained data showed that the carbazole-based Schiff base acted as an ideal chemosensor for Al3+.eninfo:eu-repo/semantics/closedAccessCarbazoleAl3+Limit of detectionFluorescence probeSchiff baseArticle3262097210610.1007/s10895-022-03008-yQ3WOS:0008347167000012-s2.0-8513745648335915282Q3
