| 摘 要： | 对具有水解性质的铝、锰离子对交换吸附研究的结果是 ,两种离子既表现了离子交换的一般化学行为 ,又有明显的非等当量交换和非电性吸附的特征 ;非等当量交换和非电性吸附受制于固相的表面性质、离子对的相对交换能力和离子的加入量 ;对非电性吸附的有关参数k、K、1/n、r和ΔF进行了表述 ;根据铝离子交换锰离子的ΔF ,从热力学论证了红壤对铝离子的吸附是自发和不可逆的并趋向稳态的自然过程

| Abstract: | The results on exchange-adsorption between aluminium and manganous ion in red soils were shown: These two ions expressed both chemical behaviours according to the universal rules of ion exchange and quite distinct characteristics of nonequivalent exchange. Nonequivalent exchange and its nonelectrical adsorption between aluminium and manganousion resulted from their hydrolysis nature, which were influenced by property of solid surface, relative exchange power of ion pair and ion amount added. The parameters concerned k, r, 1/n, K and ΔF were also explained. In view of ΔF, the processes which were spontaneous and irreversible towards stable state for exchange of manganous ion by aluminiun and adsorption of aluminium by red soil were demonstrated in thermodynamics. |
