摘要
介绍利用兰州连华科技5B-1型消解器和自制药品可满足废水监测分析的COD快速测定。该方法测定平行样相对标准偏差≤4.17%(n=5),加标回收率为96%-104%,与标准方法相比无明显差异。
The paper introduces COD quick determination satisfied waste-water monitoring analysis by using 5B-1type digester of Lanzhou Lianhua Sci-tech and self-making medicine. This method measure parallel sample relative standard deviation is less than or equal to 4.174%(n=5), adding standard recovery is 96%-104%, there is no significant difference contrast with standard method.
