Abstract: lhe run and analytical application of oxidation reaction of promazine (PM) and thioridazine (TR) hydrochlorides with iron (III) and ferrocyanide (III) are described. The coloured products of oxidation absorb at 5 12 nm for promazine and 634 nm for thioridazine. This property is a basis of a rapid, accurate and sensitive spectrophotometry method for determination of these phenothia/. ines. The elaborated methods allow to determine 3-28| ...
