摘要: A method is presented for the simultaneous determination of a wide range carboxylic acids and phenols in water. Extractive alkylation used with tetrabutylammonium ion as counter pentafluorobenzylbromide alkylating agent. Extracts are analyzed by glass capillary gas chromatography electron capture detection. Using one ml water sample, detection limit lies 1–10 μg/l. Application has been made to analysis steam condensate domestic sewage effluent.
