Abstract: Two flow injection methods are described for the determination of the antioxidants, t-butyl-4-methoxyphenol (I) and 2,6-di-t-butyl-p-cresol (II) and I in the presence of II. Sample solution containing I was injected into a carrier stream of 0.1 M perchloric acid - 5% methanol and the oxidation signals wer recorded at +0.8 V (in the absence of II) and +0.6 V (in the presence of II). The same procedure was used to determine II, with the oxidation signal being recorded at +1.05 V. The calibration graphs were rectilinear for 0.01 to 0.1, 0.1 to 1 and 1 to 10 mg L-1 of I and 0.02 to 0.1, 0.1 to 1 and 1 to 8 mg L-1 of II. The determination of I in the presence of II is possible as the former is more easily oxidized than the latter. The method was used in the analysis of maize oil and commercial ethyl ether.
