微波加热回流法合成Mg-Al二元类水滑石化合物

摘要

Mg- A1- hydrotalcite- like compounds were synthesized by a microwave-assisted heating reflux process. All synthesized compounds were characterized by X-ray powder diffraction （XRD） technique. XRD certified that all samples were well crystallized hydrotalcite - like compounds. In addition, the effects of the heating intensity, the reaction time and the medium pH value on the structure of Mg - AI - hydrotalcite - like compounds were also studied.%采用微波加热回流法合成镁铝型二元类水滑石化合物.利用X-射线衍射分析（XRD）对合成产物进行表征.结果表明,合成样品均有水滑石的层状结构,结晶良好.此外,本研究还探讨加热强度、反应时间和反应体系的pH对合成产物结构的影响.
