Аннотация:Thermal lens spectrometry was used for the differential kinetic determination of aniline (over the concentration range of 8 x 10(-4)-3.2 x 10(-3) M) and 4-nitroaniline (2 x 10(-4)-1.6 x 10(-3) M) present in combination in a single sample based on the oxidation reaction with periodate ions in an acidic medium (this determination is not possible with the spectrophotometric monitoring of the rate of reaction). The thermal lens procedure (lambda(e) = 488.0 nm; 80 mW) was characterized by good performance characteristics in the determination of aniline (c (min) = 3 x 10(-4) M; c (d) = 8 x 10(-4) M) and 4-nitroaniline (c (min) = 7 x 10(-5) M; c (d) = 2 x 10(-4) M), simplicity, and rapidity.
