请帮帮翻译一段长话hydrogen peroxide in sodium percar ...? 首先谢谢各位的热心帮助。 通过大家的指导,我基本明白了此句话的意思,应该和niuky说的差不多“来自过碳酸钠中活性氧浓度可以通过分析过氧化氢的容量得到,该容量分析可通过还原4价铈盐为3价铈盐的铈量法,或者通过氧化碘化物产生碘然后用硫代硫酸钠溶液滴定释放出的碘的碘量法。” also the active oxygen concentration in sodium percarbonate can be obtained from accurate volumetric analysis of hydrogen peroxide and accurate volumetric analysis of hydrogen peroxide can be carried out by reducing ceric salts to cerous salts or by liberating iodine from an iodide, followed by titration with a thiosulfate solution.查看更多
