Abstract:

In this paper, phenolphthalein and thiophene hydrazide are used as raw materials to design and synthe-size a fluorescent probe (FS) that can selectively detect trace amounts of Al3 + ions in dimethyl sulfoxide and ethanol. After FS is combining with Al3 + ions, the photo induced electron transfer (PET) is inhibiting, so it emits strong blue fluorescence (453 nm) to realize the specific detection of Al3 + ions. Tested by Job's plot and Benesi-Hildebrand method, the binding ratio and binding constant of FS and Al3 + ion are 2:1 and 5.6 x 10 5 M -1, respectively. As shown by the fluorescence gradient concentration testing, the min-imum detection limits of FS in DMSO and ethanol were 2.75 x 10 -8 M and 1.8 x 10 -8 M, respectively, both of which were lower than the WHO standard for Al3 + ions in drinking water (7.41 mu M). FS fluores-cent probes can be prepared as detection solvents and test strips for a wide range of applications in the detection of trace Al3 + ions.(c) 2022 Elsevier B.V. All rights reserved.
