1.To absorb aceticacid in ambient air and waste gas by distilled water,to separate by packed column of 5 % PEG 2 0M + 0 .5 %H3PO4 Chromosorb HP 80～ 1 0 0mesh ,to detec tby FID ,and to determine by GC .
2.This paper used 2m×?3mm glass column packed with 0.5% EGA on 80～100 mesh Gaschrom Q and isooctyl alcohol as the internal standard to separate allyl isothiocyanate and allyl thiocyanate .
