标准摘要
[中文适用范围]： 该测定包括过氧水合物和高锰酸钾在酸性溶液中的共还原，同时释放氧气。 由于洗衣粉的特殊性和过氧水合物的相对稳定性，洗衣粉的溶解很可能不完全，并可能导致氧气的损失；通过采用适合测定活性氧含量的特殊溶解方法，避免了这些缺点。 该方法可用于测定过氧水合物，例如过硼酸钠。 [外文原描述]： The determination consists in co-reduction, with liberation of oxygen, of the peroxyhydrate and potassium permanganate in an acid solution. Because of the specifity of washing powders and the relative stability of peroxyhydrates, the dissolution of washing powders is likely to be incomplete and may result in a loss of oxygen; these disadvantages have been avoited by adoption of a particular method of dissolution appropriate to the determination of active oxygen content. This method may be used for determing peroxyhydrates, for example sodium perborate.
