[Inhibitory kinetic fluorimetric determination of trace aniline].
An inhibitory kinetic fluorimetric method is reported for the determination of trace aniline. The proposed method is based on the inhibitory effect of aniline on the reaction of potassium periodate oxidation of rhodamine 6G in phosphoric acid medium. The detection limit is 7.2 ng x mL(-1), the linear range of the determination is 0.010-0.183 microg x mL(-1). This method has been applied to the determination of trace aniline in phenolic tubes and water samples with satisfactory results.
