초록
A gas chromatographic method for the determination of airborne formaldehyde was established. In order tobe highly detectable with the electron capture detector, formaldehyde was derivatized to its pentafluorobenzyloxime form by reacting with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride(PFBHA) at pH of4.6 and temperature of 50C for 1hour. Air samples were collected into a Tedlar bag followed by transferringinto water contained in two impingers in series. Collection efficiency in the front trap was higher than 90%.Measurement of selected indoor and outdoor air samples showed higher formaldehyde concentrations in indoorair environments and the importance of ventilation for reducing indoor pollution.
