      The GB/T 15516-1995 standard specifies a method for the determination of formaldehyde content in the air, using the Spectrophotometric method, spec-trophotometry of acetylacetone. This method uses formaldehyde and acetylacetone to react under specific conditions to generate color-developing substances. Absorbance is determined by spectrophotometer to determine the concentration of formaldehyde. This standard is applicable to air mass monitoring, indoor environment testing and other fields, providing a scientific basis for evaluating the potential impact of formaldehyde on human health.
