| 摘 要： | 本文研究利用微波程序升温法对固体废弃物样品进行消解,并采用偏钼酸铵分光光度法测定固体废弃物中总磷的含量。方法检出限为0.06mg/L,回收率为87.6%-105%,相对标准偏差小于6.2%。该方法简单、准确、稳定,可作为测定固废中总磷含量方法研究的参考。

| Abstract: | Programmed temperature microwave digestion was applied in the determination of total phosphorus in industry solid waster by metamolybdate spectrophotometry.The detection limit of this method was 0.06mg/L,the recovery rate was between 87.6%,and 105%.The relative standard deviation(RSD) was less than 6.2 %.This method is simple,accurate and stable,and it can be used in measuring the content of total phosphorus in industry solid waster. |
