Detection of Adulterated Diesel Using Fluorescent
Test Strips and Smartphone Readout
Posted on 2017-10-19 - 18:06
The fluorescence
properties of three molecular rotors, related
to 4-dimethylamino-4-nitrostilbene (4-DNS), are studied versus different
diesel/kerosene blends. In nonviscous solvents, these compounds can
populate a twisted intramolecular charge transfer state which deactivates
nonradiatively, successfully suppressing fluorescence emission. Solution
experiments with diesel/kerosene blends showed a good linear correlation
between the fluorescence intensity of the probe molecules and the
diesel fraction of the blend. The dyes have been immobilized on paper,
retaining their fluorescence behavior, i.e., negligible emission in
the presence of nonviscous organic solvents and increasing fluorescence
when the environment is increasingly viscous. When the impregnated
paper is devised as a test strip, the latter is compatible with a
newly designed smartphone reader system, which allows in-the-field
measurements. The method can safely detect the presence of kerosene
in diesel at ≥7%, which competes favorably with current standard
methods for the detection of diesel adulteration.
