摘要: Abstract Low concentrations of aldehydes and ketones in aqueous samples are concentrated on a small column containing zeolite known as ZSM-5. The carbonyl compounds then eluted with volume acetonitrile converted to the 2,4-dinitrophenylhydrazones, which separated by liquid chromatography. Excellent recoveries obtained for all studied exception formaldehyde. method has been used analysis drinking water samples.
