溴水氧化—磷钼蓝分光光度法测定水和废水中元素磷

Measurement of Elemental Phosphorus in Water and Wastewater by Using Spectrophotometric Method

对元素磷水样的采集方法进行了比对;对其测定条件进行了试验;提出有机磷农药对元素磷测定无干扰;在应急监测时可减少水样的清洗次数;该方法的检出限为0.019mg/L、样品的加标回收率为92.69%～97.70%。

The collection methods for water sample containing phosphorus are compared.The experiements for studying the measurment conditions show that there is no disturbance in the measurement of elemental phosphorus by organic phosphorus pesticides.Therefore,the cleaning times of water samples could be minimized in the emergent conditions.The detection limit of this method is 0.019mg/L and sample recovery rates of standard control are from 92.69%to 97.70%.
