Notes

Abstract:
The purpose of this research project was to replicate the synthesis and test for the effectiveness of an Al3+chemical sensorunder weak, acidic, aqueous conditions. Aluminum has been shown to effectively bind to two sites on the sensor, 4-(8’-hydroxyquinolin-5’-yl)methyleneimio-1-phenyl-2,3-dimethyl-5-pyzole, in order to draw the lone pair of electrons on the nitrogen away from the chromophore sites to release luminescent emission energy that is then measured to detect the presence of Al3+. This chemical sensor’s viability was then tested under various conditions, including different concentrations of ions and under the presence of different metal ions with varying charges. Findings were consistent with the proposed chelation enhanced luminescence phenomena that was reported in the literature. Measurable quantitative differences were found upon the addition of Al3+, no matter which ion was contaminating the solution at the time. All work was completed, synthesized, and tested at Middlesex County College’s chemistry laboratories. This includes the use of various measurement devices, including Nuclear Magnetic Resonance Spectroscopy, Ultraviolet Visible Spectroscopy, Fluorescent Emission Spectroscopy, and of course, other devices used to prepare the sensor, including a rotary evaporator and the use of column chromatography.This experiment was first conducted by X. Jiang, B. W. et. Al. (2011). 8-hydroxyquinoline-5-carbaldehyde schiff-base as a highly selective and sensitive Al3+ sensor in weak acid aqueous medium.
