The Study on the Spectrophotometic Determination of Formaldehyde in Water-Fat Foods by Acetyl Acetone

Acetyl acetone as chromogenic reagent,a method of determinating the formaldehyde in water-fat foods was established.The results indicated that the best determination condition of this method was that λmax was 412 nm,the volume of chromogenic reagent was 3.00 mL,the temperature of water bath was 60 ℃,and the reaction time was 3 minute.There was a good line relationship of absorbance of the formalde…
