4-氨基安替吡啉法广泛应用于工业废水及其他水质中酚类的测定。但须用铁氰化钾作氧化剂,测定过程中产生氰化物污染环境,而且处理困难。宫本邦彦等曾用过氧化酶和过氧化氢代替铁氰化钾,但其温度、pH等条件要求严格。作者采用碘作为氧化剂得到同样的效 4-Aminoantipyrine method is widely used in the determination of phenols in industrial wastewater and other water quality. However, potassium ferricyanide should be used as oxidant, cyanide produced in the process of pollution of the environment, but also difficult to handle. Miyamoto Kunihiko and other used oxidase and hydrogen peroxide instead of potassium ferricyanide, but its temperature, pH and other conditions demanding. The author uses iodine as the oxidant to get the same effect
