| Abstract: | Use flow injection analysis,and in-line cyanide distillation,the total cyanide in environmental water samples was determined.Linear curve was obtained in the range of 2～200 μg/L with a good linearity,the correlation coefficient was above 0.999 and the limit of detection was 2.0 μg/L.The average recovery range of cyanide in environmental water samples was 92.6%～108.2%.The method was rapid,precise and convenient and was applied to the determination of total cyanide in environmental water samples with good results. |
| Keywords: | flow injection analysis total cyanide in-line distillation environmental water samples |
