| Abstract: | The trace acetic acid in ambient air was adsorbed by sorbent sampling tube with padding of porous polymer polystyrene,and the samples desorbed through automated thermal desorber,then was separated by strong polarity chromatographic column,and was detected by flame ionization ditector.The minimum detection concentration of the method was 0.10mg/m3,RSDs were less than 5%,and recoveries were in the range of 86.2%—105.2%.The method is simple and fast,and can be applied to monitoring the trace acetic acid in ambient air with the actual-satisfied determination results. |
