【摘要】 本文首次合成了新型无机离子交换剂——锑酸锌。对交换剂的合成条件、化学组成、离子交换容量、稳定性和结构等进行了系统的探讨。在pH为3、0.5和2N硝酸介质中测定了22种金属离子的分配系数,并用锑酸锌为柱填料,成功地分离了Mn(Ⅱ)-Al(Ⅲ)、Mn(Ⅱ)-La(Ⅲ)、Mn(Ⅱ)-Fe(Ⅲ)、Mn(Ⅱ)-Cu(Ⅱ)和Mg(Ⅱ)-Fe(Ⅲ)等离子混合物。更多还原

【Abstract】 A new inorganic ion-exchanger, zinc antimonate, has been synthesized. The synthesis condition, ion-exchange capacity, and the stability and structure of the exchanger have been studied systematically. Ion distribution of twenty-two metal ions have been determined on this exchanger at pH3, os in 2M HNO3 The following mixtures have been separated. Mn (Ⅱ) - AI (Ⅲ) , Mn (Ⅱ) -La (Ⅲ) , Ma (Ⅱ) -Fe (Ⅲ) . Mn (Ⅱ) -Cu (Ⅱ) and Mg (Ⅱ) - Fe (Ⅲ) .更多还原
