Abstract:A HPLC method for the determination of hydrazine existed in the form of hydrazine hydrochloride was established. Hydrazine hydrochloride was separated and analyzed on a C18 column and UV-absobance detector at 220 nm, while the mixture solution of acetonitrile and 0.2 mol/L ammonium formate aqueous solution (pH=5.3) was used as the mobile phase. The results showed that the retention time of hydrazine hydrochloride was of 6.4 min; and the linear correlation coefficient was 0.999; The standard deviation was of 0.11; the variation coefficient was 0.12%, and average recovery was 100.15%. This method was simple, rapid, stable and easy to operate, which was suitable for quantitative analysis.
