Abstract:The determination of 1,4-bis(4-amino-2-trifluoromethylphenoxy)benzene(6FAPB) was performed using Hypersil BDS C18 column(4.6 mm×200 mm, diameter 5 μm) as the separation column, acetonitrile-water (v:v=60:40) as the mobile phase, and 252 nm as the detection wavelength. In a concentration range of 0.24~0.48 mg/mL, the calibration curve with correlation coefficients of 0.9998. Their recoveries ranged from 98.35% to 99.93% with a relation standard deviation of below 0.63%(n=5) were achieved. This method was proved to be a simple and fast method for the determination of 6FAPB. |
