土壤通报1959年4期由中国科学院林业土壤研究所俞铭钦、王芳英二同志合作的“全量分析法中硅、铁、铝快速连续测定法”一文,我认为是值得在农业化验工作中推荐的方法,因为该法操作迅速,简便易行.但我认为该文的铁铝计算是错误的.1.根据定量分析教科书和叶炳同志在土壤通报1960年6期上的介绍,EDTA与极大部分阳离子相络合,不论金属的原子价如何,一律都是1:1克分子关系.其反应式如下:
Soil Bulletin 1959 4 Paper titled “Fast and Continuous Determination of Silicon, Iron and Aluminum in Total Analysis” by Yu Mingqin and Wang Fangying, two comrades of the Institute of Forestry and Soil Science, Chinese Academy of Sciences, I think it is worth recommending in the field of agricultural laboratory work , Because the method is quick and easy to operate, but I think the iron-aluminum calculation in the paper is wrong.1 According to the quantitative analysis of textbooks and Ye Bing’s introduction in Soil Bulletin, 1960, Cationic phase complex, regardless of the valence of the metal, are all 1: 1 molecular relationship.The reaction is as follows:
