用X-mate^(pro)仪测定废水中的氨氮浓度

DETERMINATION OF NH_3—N CONCENTRATION IN WASTE WATER WITH X-MATE^(PRO)

介绍用X-matepro仪测定废水中的氨氮浓度的方法。实验结果表明,该法可满足废水中氨氮浓度快速检测要求,可根据氨氮浓度的高低、样品来源合理选择添加硫酸铝溶液,样品浓度超高时必须进行稀释,避免电极受污染。

Presents a method of determining NH3-N concentration in waste water with X-matepr^pro. It is indicated by experimental results that this method can satisfy the demand of fast determination of NH3-N concentration in waste water. With this method, alunfinium sulfate can be used according to NH3-N concentration and sample sources. The sample must be diluted when its concentration is too high to avoid the electrode from being polluted.
