AB  - A method for the simultaneous determination of six UV filters in cosmetics by 
      high performance liquid chromatography (HPLC) coupled with solid-phase extraction 
      (SPE) based on graphene sponge (GS) was established. The samples were extracted 
      with methanol by ultrasonic, then cleaned up by home-made SPE cartridges and 
      eluted with acetone. The six UV filters were separated on an Agilent Zorbax 
      SB-C18 column (150 mmx4.6 mm, 5 mum). Methanol-water (95:5, v/v) was used as 
      mobile phase and the detection wavelength was 340 nm. The results showed that the 
      limits of detection (LODs, S/N=3) and the limits of quantification (LOQs, S/N=10) 
      of the six UV filters were 0.08-1.82 mug/L and 0.26-6.07 mug/L, respectively. The 
      correlation coefficients (r) were greater than 0.999 except 
      2-(2'-hydroxy-5'-methyl-phenyl) benzotriazole (r>0.997). The recoveries of the 
      six UV filters were 61.1%-119.0%, and the relative standard deviations (RSDs) 
      were less than 1% (n=6) at the three spiked levels of 20, 50 and 100 mug/L. The 
      method is simple, rapid, sensitive and repeatable, and is suitable for the 
      determination of the UV filters in cosmetics.
