| Abstract: | A method was developed for detecting nitrite in oil-based cutting liquid and machining process waste fluid using ion chromatography. In the paper, water was used as extracting agent and the extraction conditions were optimized. The detection limit of this method was 0.015 mg/k. The recovery of nitrite in samples was 90.9 %~ 100.9 %, and RSD was 1.04 %- 1.76 %. |
