Abstract
An ATR-FTIR-spectroscopic sensor for aldehydes and ketones in solutions is presented. A germanium-ATR-crystal was coated with polymethacrylic acid hydrazide, which is crosslinked on the crystal surface. The spectral changes after the reaction of polymethacrylic acid hydrazide with various carbonyl compounds such as formaldehyde, benzaldehyde and acetone were investigated and the regeneration of polymethacrylic acid hydrazide was shown. Measurement series for propionic aldehyde in the range of 1 to 20%w/v were realized and could be quantified easily with good reproducibility but relatively high response time.Keywords
