Molecules, Vol. 23, Pages 2646: A New Environmentally-Friendly Colorimetric Probe for Formaldehyde Gas Detection under Real Conditions Molecules doi: 10.3390/molecules23102646 Authors: Carlos Martínez-Aquino Ana M. Costero Salvador Gil Pablo Gaviña A new environmentally-friendly, simple, selective and sensitive probe for detecting formaldehyde, based on naturally-occurring compounds, through either colorimetric or fluorescence changes, is described. The probe is able to detect formaldehyde in both solution and the gas phase with limits of detection of 0.24 mM and 0.7 ppm, respectively. The probe has been tested to study formaldehyde emission in contaminated real atmospheres. The supported probe is easy to use and to dispose, and is safe and suitable as an individual chemodosimeter.
