| Abstract: | The exhaust from pathalic anhydride plant goes through a vessel containing absorbent A and ο xylene, the content of ο Xylene in the absorbent is analyzed by gas chromatography. The standard deviation factor is 1.43%,the minimum detect limit is 1μg/L,the recovery is between 96.8% ～ 101.6%.Being simple and accurate, this method can be applied easily. |
