GB/T 7491-1987 《Water quality--Determination of volatile phenolic compounds--After distillation with bromine method》 Related products

This standard applies to the determination of industrial wastewater containing high concentrations of volatile phenols. After the volatile phenols are distillated with water vapor, they react with bromine to produce tribromophenol, and the remaining bromine is titrated by volumetric method to calculate the phenol content. This method is suitable for the quantitative analysis of volatile phenols, and it is necessary to pay attention to the interfering substances in the distillation process and deal with them appropriately.
