pH-based colorimetric detection of monofunctional aldehydes in liquid and gas phases

An ammonium chloride–Congo red (NH4Cl-CR) solution is presented as a potential sensing solution for aldehydes. Monofunctional aldehydes such as formaldehyde, acetaldehyde, benzaldehyde, and isobutyraldehyde caused changes in the pH of the sensing solution, producing a color transition from red-orang...
