Single-column ion chromatography with determination of hydrazoic acid produced in spent nuclear fuel reprocessing
Description
The reaction of hydrazine and its derivative with ammonium metavanadate may produce hydrazoic acid (HN3). A single-column ion chromatography is used for the determination of HN3 after neutralizing the rest acid in the sample with sodium hydroxide. Chromatography separation of HN3 is carried out on a 25 cm x 0.46 cm (inside diameter) stainless steel column packed with Vydac IC302 ion Chromatography packing. The eluent is 1 mmol/L o-phthalic acid, and the ion is detected by conductivity detector. The detection limit in the presence chromatography is 5 μg/mL, the linear range is from 5 to 201 μg/mL, the linear correlation coefficient is 0.9994, respectively. The analysis accuracy is 2% for standard sample, and the detection limit is 51 μg/mL for HN3 in the real sample. (authors)
