摘要
The conditions for the derivatization of hydrazine with p-dimethylaminobenzaldehyde and 4-chloro-5,7-dinitrobenzofurazan, extraction preconcentration of derivatives from natural water, and HPLC determination of the toxicant with diode-array detection were studied. The 5,7-dinitrobenzofurazan derivative was quantitatively extracted from water with isoamyl alcohol and a mixture of isoamyl alcohol with methylene chloride at pH 3-4. A procedure was developed for the extraction-chromatographic determination of hydrazine in water with c(min) = 0.05 mu g/L and the analytical range 0.12-60 mu g/L. The concentration of hydrazine in lake Kaban water was determined.
