本文讨论了如下几个问题: 1.考虑了前人沒有考虑到的平衡,推导得了一个对于螯合萃取理論的一般方程式。前人的結果只是我們方程式的簡化情况。2.推导出了一个关于离子締合萃取理論的一般方程式。3.推导出了用pH单位表示萃取范圍的一般方程式岢鲈谟行┣榭鱿?可以用浓度单位或容积单位来表示萃取范圍,并推导得了一般方程式。4.还討論了几个其他的萃取理論問題。 This paper discusses the following questions: 1. Considering the balance that our predecessors did not consider, we derive a general equation for chelating extraction theory. The result of our predecessors is only a simplification of our equations. 2. Derive a general equation about ion association extraction theory. 3. The general equation for the extraction range expressed in pH units is derived. The extraction range can be expressed in terms of concentration units or volume units and the general equation derived. 4. Several other extraction theory issues are also discussed.
