原子指数与镧系离子理化性质的相关性研究

Correlation Studies Between Atomic Index and the Physicochemical Properties of Ln^(3+) Ions

原子指数G定义式为G =ni+∑eij1+mi,G不仅对 3价镧系离子Ln3 + 实现唯一性表征 ,而且与其 6种理化性质显著相关 .特别是与Ln3 + 离子的离子半径、水化能的相关系数高达 0 .9994、0 .996 2 .本方法还具有计算简单、应用方便等优点 .

A atomic index G is defined as G=n i+∑e ij 1+m i,which has good structural selectivity and marked relation with the 6 physicochemical properties of Ln 3+ ions.The correlation coeficients r + and △ H with G are 0.999 4 , 0.996 2, respectively. It has been demonstrated that the method possesses the advantages of easy computation and convenient application.
