化学世界第八卷第十期“用过碘酸快速分析甘油法”一文刊出后,我厂即进行实验。这方法既准确,又迅速,对生产方面有很大的帮助。我们采用此法已有一年多了,在日常分析工作中也发现一些问题,为了相互交流经验,特提供大家参考和讨论。过碘酸钾与甘油起氧化作用后,一部份还原成碘酸钾,所以在溶液中有过剩的过碘酸钾与碘 Eighth World Chemical World Volume tenth “A rapid analysis of glycerol using peridic acid ” article published, my factory that experiment. This method is both accurate and rapid, which is of great help to production. We have adopted this method for more than a year. We have also found some problems in our daily analytical work. In order to exchange experiences, we provide references and discussions. After the oxidation of potassium periodate and glycerol, part of the reduction to potassium iodate, so there is excess in the solution of potassium periodate and iodine
