Abstract:
A reliable UPLC-MS method was developed for the simultaneous determination of 4 chemicals (Sudan Ⅰ, tetrabromobisphenol A, tris ( 1, 3-dichloroisopropyl ) phosphate and tris ( chlorisopropyl ) Phosphate) in children products. The samples were ultrasonic extracted with acetonitrile, and then the four chemicals were separated on a C18 column in 3 min. Results showed that the limit of quantification of the method was between 5 and 500μg/kg. The calibration curves were linear within 2-3 orders of magnitude with typical correlation coefficient above 0 . 9995 . The recoveries ranged from 83 . 7% to 97 . 8% with three addition levels. The sensitivity, recovery and selectivity of the method could fully meet the requirements of practical work.
