METHOD AND KIT FOR MEASUREMENT OF FORMALDEHYDE IN AIR

摘要

The present invention relates to a method for selectively measuring the formaldehyde in the air. More particularly, the present invention is non-3-methyl-2-benzothiazolinone hydrazine hydrochloride (3-methyl-2-benzothiazolinone hydrazine hydrochloride: MBTH) preparing a solution; After the absorption no infiltration in the MBTH solution was exposed to the atmosphere step of selectively absorbing the formaldehyde in the atmosphere; Formaldehyde is selectively absorbed by infiltrating a room absorbed in MBTH solution phase, eluting the reaction product of formaldehyde -MBTH; This eluent to put the oxidant to form the oxidation reaction of the cationic dye (cationic dye) in blue; And such cation comprising the step of measuring the concentration of the dye using a spectrophotometer, the present invention relates to a method of measuring the concentration of formaldehyde in the air. In addition, the present invention also provides a kit for such a formaldehyde concentration measurement. The measurement method and kit for measurement of formaldehyde in accordance with the present invention can significantly reduce the cost because they can be made from any analysis laboratory, sample collection from the work environment to the analysis to facilitate easy monitoring by experts and There are a lot of leverage effect on the general public and students of the science lab and indoor pollution and human health impact assessment.
