本标准适用于地表水、地下水、生活污水和工业废水中氨氮的测定。
当检测光程为10mm 时，本方法的检出限为0.01mg/L（以N 计），测定范围为0.04mg/L~5.00mg/L。

Scope

This standard specifies the flow injection analysis-spectrophotometric method for the determination of ammonia nitrogen in water. This standard is applicable to the determination of ammonia nitrogen in surface water, groundwater, domestic sewage and industrial wastewater. When the detection optical path is 10 mm, the detection limit (in N) of this method is 0.01 mg/L, and the determination range is 0.04~5.00 mg/L.
