Spectrofluorimetric determination of acetone in water samples with solid-phase extraction and a new benzaldehyde derivative

Year: 2024

Type: article

Abstract: A new method is described for acetone (C(CH3)2O) determination in various types of water, based on the reaction with 4-(dimethylamino)benzaldehyde (DMAB) in dimethyl sulfoxide (DMSO) in slightly basic medium, resulting in a highly fluorescent compound with fluorescent wavelengths free from interferences of most other compounds. Experimental conditions were optimized (reagents concentrations, reaction time) to reach optimal sensitivity. For the analysis of aqueous samples, a preconcentration step of acetone by solid-phase extraction (SPE) followed by an elution step in DMSO were optimized using Isolute ENV+ columns. A highly satisfactory low detection limit of 0.014 µM (0.8 µg L-1) was achieved by combining these two steps, and the protocol was validated on complex real water samples such as river water and wastewater.
