Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] The invention discloses an air formaldehyde self-test box, which includes an absorbent, an acidifying agent, a diluent, a color developing agent and a color comparison card. The principle of the self-test box is to use formaldehyde in the air to react with 3-methyl-2-benzothiazolone hydrazone (referred to as phenol reagent) to form oxazine, which is oxidized by ferric ions in acidic solution to form a blue-green compound. The color depth is directly proportional to the content of formaldehyde, and after 30 minutes of color development time, it can be quantified by colorimetry. The principle is based on the national standard method "Phenol Reagent Spectrophotometric Method for the Determination of Formaldehyde in the Air of Public Places" (GB / T18204.26-2000).
[0020] The absorbent is selected from phenolic reagent. In order to...
