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.
