磷矿中有机质的测定

Determination of Organic Matter in Phosphate Eock

磷矿中含有的有机质影响着磷矿的生产和利用,准确测定磷矿中有机质含量具有重要意义。本文采用高温外热重铬酸钾氧化-容量法测定磷矿中有机质,结果表明,该方法具有简单、快速、重现性好等优点。

Phosphate rock containing organic matter influences the production and use of phosphate rock, accurate determination of the phosphate rock content of organic matter is important. In this paper, outside temperature hot potassium dichromate oxidation - volumetric method, determination of organic matter in phosphate rock, the results show that this method is simple, fast, and good reproducibility.
