Formaldehyde is widely used to improve textile quality, but it is categorized as a potential carcinogen in humans. The concentration of formaldehyde emitted from textile products therefore has implications for public health. The standard method uses acetylacetone for determining formaldehyde extracted from textile products, but requires a water solution and the use of an analyzer. In this study, we present a method for screening textile-emitted formaldehyde via a porous glass sensor that we previously developed. Our method is suitable for on-site screening, whereas the commonly used method is not. The glass sensor was used to measure formaldehyde concentrations emitted from several kinds of textile products. The results showed good agreement (coefficient 0.92) with those of the acetylacetone method. Moreover, we estimate the effects of temperature, and suggest a formula to calculate concentration including temperature correction.

“…Their procedure, called headspace water‐based liquid‐phase microextraction, is free of organic solvents and thus more environmentally friendly. An aqueous microdrop containing various reagents was used for the determination of arsenic , antimony , selenium , mercury , ammonia , sulfide , fluoride , chloride , nitrite , cyanide , formaldehyde , amphetamine , polycyclic aromatic hydrocarbons , terpenes , and others. An aqueous drop containing an alcohol dehydrogenase enzyme and the cofactor β‐nicotinamide adenine dinucleotide was reported as a fluorescence probe for the determination of ethanol in alcohol‐free cosmetics .…”

The present article offers a glance at achievements in single-drop microextraction(SDME), with a focus on the two most commonly used modes of this technique: headspace and direct immersion. Factors affecting SDME, such as the pH and ionic strength of the sample solution, the stirring rate, and the extraction time are briefly summarized. The requirements for the acceptor phase and the influence of the sampling temperature are presented. In addition, the potential of the application of microwave and ultrasonic energy in SDME is also discussed. Examples of the application of the headspace and direct immersion modes of SDME are given in a table as additional Supporting Information.
