抄録

A method for the determination of gaseous acrolein by gas chromatography with ECD has been developed. Sample gases (340l) were collected in absorption solution of ethanol at the rate of 0.5l/min. After 5 ml of the absorption solution was diluted to 25 ml with water, this solution was brominated at pH 2. The excess of bromine was reduced with sodium thiosulfate solution and 4 ml of phosphorous buffer (pH 8) was added. The derivative of acrolein was extracted with 5 ml of ethyl acetate for three times. The extract was made up to 20 ml with ethyl acetate and 5 μl of this solution was injected into a gas chromatograph with ECD. The lower limit of determination was about 5 nl/l at a size of 40 l of sample gas. The recovery of standard gas was 94% and the relative standard deviation was 8.7% (n=4).
