| Abstract: | According to the characteristics of formaldehyde in indoor air,formaldehyde was measured by the method of acetyl acetone with spectrophotometer,the impact of relative factors on the determination was studied,and the best experimental conditions were discussed.The results indicate that the best conditions for the determination of formaldehyde in air are as follows: reaction temperature is 60 ℃,dosage of acetylacetone is 2 mL,gas recovery velocity is 0.5 L/min.This method is simple,quick and convenient,it has high sensitivity and good reproduction. |
