Abstract: The 2. 000 g of coating sample was taken, and 15 mL of acetonitrile was added. The mixture was vortexed
for 30 s, and extracted by ultrasound at 30 ℃ for 40 min. After cooling to room temperature, the extract was made its volume
up to 20 mL with acetonitrile. An aliquot (1 mL) was taken, and passed through a 0. 22 μm filter membrane, and the filtrate
was introduced into a high performance liquid chromatograph. Three fluoroalkyl acrylate compounds (FTAs), including
1H,1H,2H,2H-perfluorodecyl acrylate (8∶2 FTA), 1H,1H,2H,2H-perfluorododecyl acrylate (10∶2 FTA), and 1H,1H,2H,2H-
perfluorooctyl acrylate (6∶2 FTA) were separated on a ZORBAX SB-Aq column by gradient elution with a mixture of acetonitrile
and water at different volume ratios, with external standard method for quantification. It was shown that linear relationships
−1
between values of mass concentration and peak area of the 3 FTAs were kept in the range of 0. 2-5. 0 mg · L , and the detection
limits (3S/N) were found in the range of 0. 27-0. 34 mg · kg −1 . Test for recovery was made according to the standard addition
method, giving recoveries in the range of 93. 5%-109%, with RSDs (n=6) of the determined values ranged from 0. 50% to
4. 7%. The proposed method was used for the analysis of 10 types of coating samples, and 8∶2 FTA was detected in two types of
samples, with detection amounts of 226. 7 mg · kg −1 and 4. 1 mg · kg −1 , respectively.
