摘　　要：建立了分光光度法测定空气中丁醛的含量。空气中的丁醛经一种溶剂型硅胶管采集、混合溶剂解吸、使用分光光度法检测。在实验确定的最佳条件下,加标回收率为94.5%~103.0%,该方法具有简单、快速、重现性好、采集效率高等优点。A spectrophotometric method was established to determine the content of butyraldehyde in air.The acetaldehyde in air was collected by a solvent type silicone tube.absorbed by a mixed solvent.and detected by spectrophotometry.Under the best conditions determined by the experiment.The recovery of standard addition was 95.8%~102.3%in experimental conditions.The method was simple,rapid and with a good reproducibility and high collection efficency.
