ABSTRACT:
A method and test kit for the detection of hydroxy substituted aromatic compounds using a titanium film (12, 23) which reacts with the compound to change the light absorbance. Preferred films are prepared by reaction of a titanium alkoxide with an aliphatic carboxylic acid. The change in light absorbance of the film is preferably detected with an ultraviolet-visible spectrophotometer. Preferably the film is provided on a transparent slide (22) or on an inside wall of a spectrophotometer cell (10). The cells (10 and 20) are provided with covers (13 and 14) for holding the solution to allow the hydroxy substituted compounds to react with the film.
