| 摘 要： | 双金属复合氧化物（ＣＬＤＨ）是一类发展迅速的无机层状材料的煅烧产物，在催化、吸附等领域已获长足进展［１］，但作为紫外阻隔材料的性能研究尚鲜见报道．本文研究了不同双金属复合氧化物的紫外阻隔性能，结果发现二价金属离子为锌离子的ＣＬＤＨ具有良好的紫外阻隔性能．实验所用试剂均为分析纯．ＣＬＤＨ由ＮａＯＨ，Ｎａ２ＣＯ３，ＭｇＳＯ４·７Ｈ２Ｏ，ＺｎＳＯ４·７Ｈ２Ｏ，Ａｌ２（ＳＯ４）３·１８Ｈ２Ｏ为原料，按文献［２］方法制备．ＺｎＯ＋Ａｌ２Ｏ３复配物是按一定比例机械混合后，研磨，并在与ＣＬＤＨ相同的条件下煅烧…

| Abstract: | The XRD patterns of different calcined layered double hydroxides(CLDH) and their ultraviolet absorbing and screening properties have been investigated. It has been found that a calcined layered double hydroxide(CLDH) containing zinc is very effective in absorbing and screening ultraviolet radiation. The crystal structure of a CLDH containing zinc is similar to that of ZnO and is not related to the crystal structure of Al 2O 3. It is not a simple combination of zinc oxide and aluminium oxide but a calcined layered double hydroxide in which part of the Zn 2 cations is replaced by Al 3 cations. |
