| Abstract: | The method was developed for determination of nitrite nitrogen in water by type auto analyzer 3 cotinuous flow injection. The method was linear to the nitrite nitrogen graphs higher precision and accuracy with in 0-5.00 mg/L concentration. Compared with determination of nitrite nitrogen by Spectrophotometry in GB/T 8538-2008 test methods of natural mineral water for drinking, the advantages of the method are auto-sampling, rapid analysis speed and lower reagent consumption, etc. It could be applied to analyze large quantity of natural spring water. |
