| Abstract: | Formaldehyde can sensitively catalyze the oxidation fading of acridine yellow by potassium bromate in sulfuric acid medium,and a catalytic kinetic photometry for determination of formaldehyde was developed.There was a good linear relationship between ΔA and the concentration of formaldehyde in the range of 5.0—150.0μg/L,and the linear equation was ΔA=0.0292＋0.0084C（μg/L） with the detection limit of 0.57μg/L.The method was used for the determination of formaldehyde in textiles,and the relative standard deviation was less than 4.50% with recovery of 96.6%—102.1%. |
