T. Fukasawa et al., THIORIDAZINE HYDROCHLORIDE AS A NEW REAGENT FOR HIGH-SENSITIVE ANALYSIS OF TRACE IRON, Journal of trace and microprobe techniques, 13(4), 1995, pp. 421-429
The oxidation of thioridazine hydrochloride by hydrogen peroxide is a
slow process and iron(II) has a catalytic effect on the reaction rate.
The reaction is followed spectrophotometrically by measuring the incr
ease in absorbance at 635 nm. Under the optimal experimental condition
s iron(II) is determined between 0-15 ppb. The influences of reaction
variables, the precision and accuracy of the described method were stu
died.
