摘要
本文探讨有机化合物理论化学需氧量(ThOD)的涵义,有机物各组成元素氧化达到最高氧化值应是ThOD的计算基础。重铬酸钾法实测化学需氧量(CODcr),对结构较简单的有机物接近ThOD,对结构复杂的有机物,CODcr只达到ThOD的90%或更低一些。
The meaning of the theoretical chemical oxygen demand (ThoD) is discussed in this paper.The highest oxidation value for elemental compostions of organic compounds is the mathematical calculation foundation of ThoD. CODcr for organic compounds of simple construction is well comformed to the ThoD.But the ratio of CODcr to ThoD for complex compounds is about 90% or less.
