Detection method for determining content of carbonyl metal compound

The invention discloses a detection method for determining the content of a carbonyl metal compound, and mainly solves the problem that the specific type and the target content of the carbonyl metal compound cannot be quickly, simply and conveniently provided in the existing method. The method comprises the following steps: (1) preparing a standard solution of carbonyl metal series compounds; (2) separating and determining a series of carbonyl metal compounds by high performance liquid chromatography; (3) drawing a series of standard curves of the carbonyl metal compounds; and (4) carrying out qualitative and quantitative calculation on the to-be-detected sample. According to the method, the content of the carbonyl metal compound can be directly measured through the high performance liquid chromatography, the method has good resolution capability on various impurities of VIB family homologues, the method is simple, convenient and rapid, the accuracy is high, the reproducibility is good, complex pretreatment o
