Abstract
4-Bromodiphenyl ether is a persistent organic environmental pollutant. It is the metabolism of polybrominated diphenylethers, which are widely used as bromine-based fire retardants. The preparation of certified reference material is of great significance for the related research and detection of bromine-based fire retardants. Characteristics, category and function of 4-bromodiphenyl ether certified reference materials are introduced. Two independent methods, the mass balance method and differential scanning calorimetry method, were optimized and applied to determine the purity value. As a result, the mass fraction was determined to be 0.992 ± 0.006. The process was in accordance with the Acts for Management of Reference Materials, and the 4-bromodiphenyl ether reference material was approved as a grade secondary reference material by the State Administration for Market Regulation of China with the certificated number GBW (E) 084477.
