化学需氧量——碱性高锰酸钾法(COD_(Mn))的不确定度评定

Assessment of uncertainty of COD_(Mn) by potassium permanganate method

本文根据GB17378.4.32-2007《化学需氧量-碱性高锰酸钾法》的要求,通过对各步骤的测量不确定度的具体分析与计算,得出化学需氧量测量——碱性高锰酸钾法的不确定度的数值。

The uncertainty of CODMn by potassium permanganate method was obtained by analyzing and calculating uncertainty of different steps according to GB 17378.4.32-2007〈Chemical oxygen demand- potassium permanganate method 〉.
