摘要： 用中温水热法合成了类水滑石[CdxMg6-xAl2(OH)16]2+[S·2H2O]2-,探讨了pH值、投入Cd2+离子的量以及硫化时间等条件对合成的影响,并用XRD、FT-IR、DTA-TG等手段进行了表征,找出了合成层间嵌入S2-离子的含Cd类水滑石的最佳条件。

Abstract: Hydrotalcite-like [CdxMg6-xAl2(OH)16]2+[S·2H2O]2- was synthesized hydrothermally and characterized by means of XRD,FT-IR,DTA-TGetc.,The influence of pH,Cd2+ ionic concentration and sulphuration time on the synthesis was studied.The synthetic optimal conditions are pH=9～10,[Cd2+]/[Mg2+]=1:5～1:9 and sulphuration time 5 min.It is suggested that Mg2+ ions can be only partially substituted by Cd 2+ ions in the hydrotalcite-like.

Key words: Hydrotalcite, Sulphuration, Layered compound, Synthesis
