Abstract:Two spectrophotometric methods MBTH and acetyl acetone methods were compared and studied. The influence factors, sensitivity, detection limit, detection minimum limit, accuracy, fineness of the two methods were also described. Sampling method for formaldehyde in air was established. The formaldehyde content in air was determined by two methods respectively, and the results were in accordance.
Keywords:MBTH  acetyl acetone  formaldehyde
