KHm溶液的光密度与K^＋含量的关系

Relationship Between the Optical Density of KHm Solution and the Content of k~+

用不同浓度的氢氧化钾溶液和相同重量的风化煤，配制成不同浓度的腐植酸钾溶液，并用７２－１型分光光度计测定了它们的光密度；用四苯硼钠法测出了ＫＨｍ中的钾离子含量。

Optical density of soluted potassium hydrate of different concentrations and that of the same amount of KHm solution of different concentrations are made from efflowrescent coal with 72-1 spectropjotometer. the content of kalium ions(K+)in KHm with the help of tetraphenylboron sodium.is determinel It can be concluded that, until a certain value, the optical density of KHm solution increases steadily,which is only relevant to the change of the concentration of KHm solution, and irrelevant to the content of K+. when this value is reached to the surpassed,the content of K+ is relevant to the Changes of the concentrations of potassium hydrate,while the optical density is irrelevant to the changes of hte concentrations of patassium hydrate.
