Abstract
Ethanol as oxygen additive has potential dangerous that might make poisonous organic compound exhaust more than that from pure gasoline fueled engines. This paper was concerned to methods research of sampling, separating and analysis of unconventional HC exhaust emission. Aimed at the difficult problem of formaldehyde measurement, author enriched formaldehyde by water and then measured by means of ultraviolet-visible spectrometer. The minimum measuring limits of formaldehyde was remarkably promoted to 0.02×10-6 (V/V). Furthermore, Solid-Phase Extraction Column which was pre-coated by dinitrophenylhydrazone (DNPH) was selected to catch aldehyde and ketone by chemical reaction which is so called ramification, and then measured by Liquid-chromatography. Up to now, more than 8 different organic have been determined. It was shown that formaldehyde as high toxicity exhaust emission was much more than that from gasoline fueled engine.
