Dissolved oxygen in water is determined by its oxidation of manganese(II) to manganese(III) in alkaline medium and formation of the red manganese(III) ethylenediaminetetra-acetic acid complex on acidification to pH 4. The range of determination is 7-3160 mug of oxygen in a final volume of 500 ml.
通过在碱性介质中将锰(II)氧化为锰(III)并在酸化至pH 4时形成红色锰(III)乙二胺四乙酸络合物来测定水中的溶解氧。测定范围为7-3160最终氧气量为500毫升。
