摘要
在用蒸馏水吸收空气或废气中的乙酸后,采用5%PEG20M+0.5%H3PO4chromo-sorbHP80～100目2m×2mm玻璃填充柱,GC直接进样测定蒸馏水中的乙酸,方法简便、快捷,变异系数为2%～5%,加标回收率为85%～106%,最低检出浓度为0.16mg/m3。
Absorbing acetic acid in air or waste gas by distilled water, acetic acid in distilled water was detected by gas chromatography with packed column of 5% PEG 20M and 05% H3PO4 on chromosorb HP 80～100 mesh packing This method is simple and rapid The variable coefficient is between 2% and 5%, recovery of added standard is between 85% and 106%, detecting limit is 016mg/L
