Formaldehyde Removal by Using Solid Phase Extraction with an Imination Reaction on an Amine Type Trident Molecule-Impregnated Resin

Abstract

Solid phase extractive removal of harmful formaldehyde with an imination reaction on a resin impregnated with a trident amine derivative has been investigated to compare the removal behavior with extractive removal with the trident amine derivative reported in the previous work. The impregnated resin also effectively removed formaldehyde while maintaining the extractive removal performance of the impregnated triamine. In particular, the leakage of the impregnated amine was significantly suppressed in the solid phase extraction with the impregnated resin compared with that in the extraction system.
