污泥中总磷测定方法的探讨

Studyon the method of total phosphor in pollute soil

污泥样品与氢氧化钠熔融,使污泥中含磷有机化合物全部转化为可溶性的正磷酸盐,然后测定污泥中的总磷含量。此方法方便易行,平行性好,准确度高,可作为测定污泥中总磷的标准方法。

If pollute soil sample is melted in NaOH , the P element in pollute soil will translate into PO43-. Total can be determined using this method. It is convenience parallel veracity and easy to do .It is the standard method of determining total P in pollute soil.
