Trace analysis of volatile organic compounds in water by GC and HPLC
Technical Report
·
OSTI ID:5161303
Low-molecular weight aldehydes and ketones were concentrated by a hydrophobic zeolite, ZSM-5. The carbonyl compounds (100 ppB) were desorbed with a small volume of acetonitrile and converted to the 2,4-dinitrophenyl-hydrazones. The derivatized analytes were recovered by solvent extraction (pentane) followed by microdistillation. The 2,4-dinitrophenylhydrazones were analyzed by reversed phase HPLC on a C/sub 18/ column at 254 nm. Good recoveries were obtained for the model compounds, except formaldehyde. The method was applied to the analysis of drinking water from Ames, IA (no aldehydes or ketones) and from Des Moines, IA (1.6 ppB butanone).
