Examination of iron (III) and hexacyanoferrate (III) ions as reagents for the spectrophotometric determination of promazine and perazine.
Iron (III) chloride and potassium hexacyanoferrate (III) have been tested as reagents for the determination of promazine hydrochloride and perazine. The methods are based on the oxidation of phenothiazines by FeCl3 and K3[Fe(CN)6] in perchloric acid medium. The optimal conditions for the formation of oxidation products of promazine and perazine were examined. The absorption spectra in the UV-VIS region were recorded.
