Embodiment 1
[0042] 1) Preparation of sample solution: Cut the paper material for cigarettes according to the regulations of YC171-2009 to obtain a sample with a length of 200 mm and a width of 40 mm. Place the sample on a balance and weigh it to an accuracy of 0.1mg, and cut the sample into pieces no larger than 0.5cm×0.5cm with scissors; put the pieces in a 100mL Erlenmeyer flask with a stopper, add 20mL of water accurately, soak 30min; then accurately add 20mL of ethanol, ultrasonically extract for 30min, pass through a 0.22μm organic phase filter membrane after standing to obtain a sample solution.
[0043]2) Standard solution preparation: Weigh 18 kinds of PAEs standard products and dissolve them in aqueous ethanol solution. The volume ratio of water to ethanol is 1:1-2. 5ng / ml, 10ng / ml, 20ng / ml, 50ng / ml, 100ng / ml, 200ng / ml and 500ng / ml series of single standard and mixed standard solutions.
