Specific features of the determination of carbonyl compounds in atmospheric air

Resumo

It has been shown that the error of the determination of formaldehyde in atmospheric air depends both on the method of measurement of the analytical signal and on the conditions of air sampling. In most cases, the use of HPLC leads to underestimated results, while the application of spectrophotometry leads to overestimated results. A method has been developed for the selective determination of formaldehyde in atmospheric air using HPLC with a fluorescence detector, which can be used as a reference method.
