| Abstract: | A new method for separation and determination of bromadiolone inemulsifiable concentrate by thin-layer chromatography and ultraviolet spectrophotometry was described. The components in the emulsifiable concentrate were separated on a silicagel G plate with the mixture of methanol-ethylacetate-petroleumether (10∶20∶8) as developer.The concentration of bromadiolone was determined by UV absorption spectroscopy at 262 nm.The linear range for bromodiolone is 0.25～1.50 mg/mL with detection limit of 0.08 mg/mL. RSD was less than 1.9% (n=10) and the recovery was between 97.1%～102.1%. |
