“…The use of the Fenton's reagent (FR), a mixture of H 2 O 2 and Fe 2+ , for the kinetic determination of individual chemical species was proposed by G. López-Cueto and coworkers [101]. The potential of this reagent arises from the oxidant power of intermediate species generated during the slow oxidation of Fe 2+ by H 2 O 2 , but there are very few analytical applications of the reagent in the literature.…”

This review on multi-component kinetic-based determinations covers most publications in this field during the period 2000-2007. The methodologies applied during recent years have been based on differential reaction rates for simultaneous multicomponent analysis. The literature shows a great attempt to apply chemometric methods, such as partial least squares regression, artificial neural networks, H-point standard addition and a new method involving mean centering of ratio spectra in this field. This review also describes some applications of advanced multiway analysis such as PARAFAC and NPLS from 2000 in the multicomponent kinetic analysis.

“…Perhydroxyl radical could be reacted with itself to generate excited double molecular oxygen ((O 2 ) Ã 2 ) to produce CL (Li et al 2000). There are many methods to generate free radical, for example, Fenton reaction (Brusova et al 2004;Lopez-Cueto et al 2004;Yue et al 2004) and the enzyme reaction of xanthine oxidase with xanthine (Ogawa et al 1999). Fenton reaction is the most famous reaction to produce hydroxyl radical by mixing Fe 2þ and H 2 O 2 .…”

A novel chemiluminescence (CL) reaction between hydroxyl radical and ascorbic acid is described in this paper. Hydroxyl radical generated on line by the reaction between Fe 3þ solution and H 2 O 2 solution in HCl medium could oxidize rhodamine 6G to produce weak chemiluminescence. It was found that ascorbic acid could enhance the chemiluminescence and the excited rhodamine 6G was the emitter of the chemiluminescence reaction. The possible mechanism of the CL system was also discussed. Ascorbic acid can be determined in the range of 2.0 Â 10 26 28.0 Â 10 24 mg/ml with a detection limit of 1 Â 10 26 mg/ml (3s). A complete analysis could be done in 1 minute with the relative standard deviation of 3.1% for 5.0 Â 10 25 mg/ml (n ¼ 11). In order to study the chemiluminescence reaction further, the application to the determination of ascorbic acid in food using the chemiluminescence reaction combined with flow injection is investigated.
