摘要
高锰酸盐指数,又被称为化学需氧量的高锰酸钾法。由于在规定条件下,水中有机物只能部分被氧化,并不是理论上的需氧量,也不是反映水体中总有机物含量的尺度。因此用高锰酸盐指数这一术语作为水质的一项指标,以有别于重铬酸钾法的化学需氧量,更符合于客观实际^([1])。
Permanganate index, also known as potassium permanganate method of chemical oxygen demand. Due to the prescribed conditions, organic matter in water only partially oxidized, and not on theoretical oxygen demand, also does not reflect the total content of organic matter in water scale. So this term with potassium permanganate index as an indicator of water quality, the chemical oxygen demand different from potassium dichromate, accord with the objective reality. Permanganate index in the analysis process, many factors such as： water bath in the process of heating boiler water level, water bath heating time, the concentration of potassium permanganate standard solution, titration time, the indexes of blind sample test difficulty. In this paper, the analysis of these factors, summed up the best conditions for the reaction.
