Abstract
The preferential exchange uptake of the cations Cs+, Ba2+ and Zn2+ from pure solutions by zeolite-13X follows the order Q∞ [Cs+]>Q∞ [Ba2+]>Q∞ [Zn2+], while in case of binary mixtures the order is Q∞ [Ba2+(Zn2+)]>Q∞ [Ba2+(Cs+)]>Q∞ [Cs+(Zn2+)]>Q∞ [Cs+(Ba2+)]>Q∞ [Zn2+(Cs+)]>Q∞ [Zn2+(Ba2+)]. Ba2+ uptake from mixtures shows the least suppression effect.
Abstract
Поглощение избирательным обменом катионов Cs+, Ba+2 и Zn+2 из чистых растворов цеолитом-13Х подчиняется следующему порядку Q∞[Cs+]>Q∞[Ba+2]>Q∞[Zn+2] в то время как в случае двухкомпонентных смесей имеем Q∞[Ba+2(mix Zn+2)]>Q∞[Ba+2(mix Cs+)]>Q∞[Cs+(mix Zn+2)]>Q∞[Cs+(mix Ba+2)]>Q∞[Zn+2(mix Cs+)]>Q∞[Zn+2(mix Ba+2)]. Поглощение Ba+2 из смеси обладает наименьшим подавляющим эффектом.
