dc.description.abstract The colorimetric detection of polycyclic aromatic hydrocarbons (PAHs) was achieved using photochromic compounds. This technique exploits the ability of the photochromic compound to reversibly change from a colourless to a coloured compound using ultraviolet light and visible light. In the presence of a PAH, this photoisomerization is inhibited. The degree of inhibition corresponded to the molar absorptivity and excitation wavelength of the PAH, and with a limit of detection in the micromolar range, the current method delivers a highly sensitive and selective technology. In addition, PAH mixtures were successfully identified using this method, providing a potentially fast in-field sensing technology for the identification of likely sources of spilled oil.
