| Abstract: | In this paper, we use the maximum absorbance of 3,5 - Diacetyl - 1,4 - dihydro - 2,6 - dimeth- ylpyri -dine in 412 nm, exert the good characteristic of Hantzsch reaction with formaldehyde, take the gas analysis method to determine the degree of formaldehyde pollution. The results show that the gas analysis method is a quickly determining method for formaldehyde,which has high sensitivity. |
