The result shows: in this method the nitrite content in certain domestic sewage is measured 1.161 mg·L-1, and the uncertainty from the standard material and the test standard deviation under the repeatable conditions contribute mainly to the uncertainty of measuring the nitrite content in water.
The uncertainty from the standard material generally includes the uncertainties from standard dilution, standard product purity and the environment temprature, in which the extraction, dilution and stability of the standard solution are the main contributors to the uncertainty from standard dilution.
