[0012] [Example 1]
[0013] Analyze a series of standard samples containing formaldehyde and acetaldehyde according to the analysis steps of the content of the invention, (a) prepare a series of standard solutions of formaldehyde, acetaldehyde and acetone. First calibrate the content of formaldehyde solution (~37% aqueous solution) according to the method specified in GB / T 9009-1998, then weigh about 100μL of formaldehyde solution, place it in a 50mL volumetric flask, and then dilute to the mark with water and shake well. Use a pipette to accurately draw 1.00 mL of the solution into a 100 mL volumetric flask, dilute to the mark with water, shake well for use, and calculate the formaldehyde content of the standard solution, expressed in μg / mL. Draw 1.00 mL, 2.00 mL, 3.00 mL, 4.00 mL, and 5.00 mL of formaldehyde standard solution into a 25 mL volumetric flask; prepare a series of standard solutions of acetaldehyde and acetone; (b) prepare 2,4-dinitrophenylhydrazine Derivatives.
