水中氨氮纳氏试剂分光光度法的不确定度评定

Uncertainty Evaluation for Determination of Ammonia Nitrogen in Water by Nessler’s Reagent Spectrophotometry Method

采用纳氏试剂分光光度法测定水样中的氨氮含量浓度,并对该方法在实验过程中影响测量结果的不确定度进行了评定。

Nessler’s reagent spectrophotometry method was used to measure the concentration of ammonia-nitrogen content in water,and the uncertainty of this method impacting the measurement accuracy during the experiment process was further assessed.
