The effect of this correction can best be appreciated by defining the non-dimensional variablesB*5BaandT*5(T(B)2Th)/(Te2Th) and plotting these as a function ofm(Fig. 2). Values ofB*from Eqs. 2 and 3 c...
微量元素铜与伊利石界面相互作用的离子强度效应
离子强度 伊利石 铜 吸附
2009/12/7
本文测定了在NaClO4和NaCl介质中离子强度对微量元素铜与伊利石相互作用的影响．所得结果为：（1）发现了新的实验现象，即离子强度效应致使交换率E（％）－pH曲线的先右后左摆动现象和离子强度效应导致等温线先下后上移动现象；（2）在NaCl介质中铜的交换率低于在NaClO4介质中的交换率，Cl－有络合效应;（3）各离子强度下的等温线均为等温线分类法中的L－F－4型，介质的离子强度不影响等温线的...
