摘要: 测定了WQD-1沸石在一价碱金属离子混合溶液中的分配系数、饱和交换量和在25℃时,NH+4/K+、NH+4/Na+交换等温线。得出该沸石一价离子选择性序列为:Cs+>Rb+>K+>Na+>Li+, Na+/K+交换自由焓变ΔG(T,P)=-6.745 KJ/mol。 |

Abstract: The distribution coefficient in alkali solution and saturated ion exchange capacity of zeolite WQD-1 are measured and NH+4/K+, NH+4/Na+ exchange isotherms are determined. The selectivity sequence for univalentions of samples of WQD-1 is: Cs+>Rb+>K+>Na+>Li+, and the free energy of Na+/K+ exchange is -6.745 kJ/mol. |
