废水中总磷测定方法的研究

Study of Method Measuring Total Quantity of Phosphorus in Waste Water

通过试验,以硝酸-高氯酸体系对水样进行预处理,确定了在中性条件下以抗坏血酸为还原剂,对废水中总磷含量进行还原显色和测定的方法;结果稳定,仪器设备简单易操作,方法可靠。

With nictric acid-strong chloric acid to give water sample a preliminary treatment,the methods to measure the total quantity of phosphorus in waste water and reduce the waste water with anti-bad blood acid as the original agent under netural conditions.The results turn out to be stable,devices are easy to handle and the method reliable.
