HJ 671-2013 in English

本标准规定了测定水中总磷的流动注射-钼酸铵分光光度法。
本标准适用于地表水、地下水、生活污水和工业废水中总磷的测定。
当检测池光程为10mm 时，本方法的检出限为0.005mg/L（以P 计），测定范围为0.020 mg/L~1.00mg/L。

Scope

This standard specifies the flow injection-ammonium molybdate spectrophotometric method for the determination of total phosphorus in water. This standard is applicable to the determination of total phosphorus in surface water, groundwater, domestic sewage and industrial wastewater. When the optical path of the detection cell is 10 mm, the detection limit of this method is 0.005 mg/L (calculated as P), and the determination range is 0.020~1.00 mg/L.
