用膜电极法测定生化需氧量（BOD_5）

The Discussion of determination of BOD_5 with DO probe method

本文讨论了角膜电极测定生化需氧量（ＢＯＤ５）方法与传统碘量法的比较。两家实验室的验证结果表明，对于地表水和废水的测定，两种方法测得结果没有明显差异，用膜电极法测定ＢＯＤ５方法的精密度和准确度可以满足实际样品的测定。

The determination of BOD5 with DO probe method has been discussed. There are no significant difference of testing results of groundwater and wastewater with probe and iodimetry methods by two laboratories.The precision and accuracy of probe method are suited to the determination of environmental salmples.
