葡萄糖与谷氨酸以 1:1 的比例配制成标准物质,用人工海水和标准物质配制成系列标准溶液,根据碘化钾碱性高锰酸钾法对系列标准溶液的测量结果,获得了海水 COD 测量不确定度在全量程范围内的分布规律,即测量不确定度在高端大不恒定,在低端小恒定.

Using the glucose and L-glutamic-acid to prepare the standard substance according to the ratio of 1:1, and the artificial seawater and the standard substance to prepare a series of standard solutions, the distribution pattern of uncertainty in measurement of seawater COD is obtained based on the measured results of the series of standard solutions by the potassium iodide-alkaline potassium permanganate determination method. The distribution pattern is as follows: Uncertainty in measurement is big and not constant at the high end, but small and constant at the low end.
