Abstract

An analytical procedure that couples HPLC with the postcolumn reaction detector of flow injection method was developed to analyze aldehydes in fogwater samples. The aldehydes were derivatized with 3-methyl-2-benzothiazolinone hydrazone (MBTH) in the reactor and detected at 640nm. The optimal condition was established and formaldehyde, glyoxal, and glycolaldehyde concentrations were determined. The data obtained by this method were consistent with those obtained by 2, 4-dinitrophenylhydrazine (DNPH) method.
