| Abstract: | The method was established for determination of trace NO2^- -N in the Yangjiaopu source water by enrichment of self-made floatation machine and spectrophotometry. The attention for operation was given. The good linear relations were obtained in range from 0 μg/L to 4.00 μg/L. The detection limit was 0. 000 2 mg/L, RSDs 2.0% -4.6% , recoveries 94.0% - 108% . |
