摘　　要：使用直接插层法制备了顺式二胺基二苯并18-冠-6(cis-DAmDB18C6)插层α-磷酸锆(α-ZrP)材料,通过静态吸附实验,对比了顺式二胺基二苯并18-冠-6插层磷酸锆材料和α-磷酸锆对Sr^(2+)的吸附性能。实验结果表明,二胺基二苯并-18-冠-6插层磷酸锆材料对Sr^(2+)的吸附平衡时间约48h,中性溶液高温有利于吸附,低温高酸有利于解吸,最大吸附容量为125mg·g^(-1),这种插层材料对Sr^(2+)的吸附能力优于α-磷酸锆。In this paper,a new composite was prepared by intercalating Cis-Diamino-2,3,11,12-dibenzo-1,4,7,10,13,16-hexacyclooctade-2,11-diene(cis-DAmDB18C6)intoα-ZrP via a direct intercalation way.The ZrP composite was used to removal of strontium ions from aqueous solution.The results indicated that the ZrP intercalated bycis-DAmDB18C6 exhibited the higher adsorption capacity for capturing of strontium ions than that of the neat ZrP.In addition,Sr 2+adsorption on the new ZrP composite is faster after intercalating of cis-DAmDB18C6.The highest adsorption capacity of Sr2+is obtained in the neutral solution at high temperature,and the maximum adsorption capacity is 125mg·g-1.
