Abstract

The invention discloses a separation and assay determination method for components of tetrabromobisphenol A. The method adopts a high performance liquid chromatograph, uses a chromatographic column with a filling agent of octadecyl bonded silica gel, takes a mixed eluent as a mobile phase, and detects the components in a tetrabromobisphenol A sample solution by adopting a gradient elute method. According to the separation and analysis method, the components of tetrabromobisphenol A can be quantitatively analyzed by using the chromatograph, and an aim of controlling the quality is achieved.
