سنتز و مطالعه برخی خواص فیزیکی و شیمیایی یک جاذب هیدروکسیدی جدید

Double Layered lIydroxides (DUll) or anionic clays have been extensively used in various fie lds as heterogeneous catalysts, sorbcnts, anionic exchangers and so on, In this research Double Layered Hydroxides pillared with carbonate and p-toluensulfonate anions were generated by coprccipitation of concentrated aqueous solutions of AI(NO)J' 91-120 and Mg(NO,),.6H20 respectively with concentrated basic solUlions of sodium carbonate and p-toluensulfonic acid at room temperature, DLl I-oxides (DLO) of each compound was prepared with a special thermal programming, In .mother part of this research. thermal interaction was used to prepare the pi liared DLHand OLO with p-toluensulfonic acid, Comparison of the size of interlayer intcrvals of DLH and pillared DLI-I (or OLO) shows that both coprccipilation and thermal methods were successful in interca lating of p-tolucnsul fon incacid.
