| Abstract: | A novel a method was developed for the determination of nitrite in environmental water samples by continuous flowing analysis (CFA).The conditions for determination was discussed and optimized.Linear curve was obtained in the range of 1.0～200μg/L with a correlation coefficient of 0.9999 and the limit of detection is 1.69μg/L(n=11).The average recovery range of nitrite in environmental water samples is 97.16%～101.52%with the range 0.7%～1.2% of RSD.The method was rapid,precise,convenient and was applied to the determination of nitrite in environmental water samples with good results. |
