Synthetic hydrotalcite
Hydrotalcite or formerly also Völknerite is a layered double hydroxide (LDH) of general formula Mg 6Al 2CO 3(OH) 16·4H 2O, whose name is derived from its resemblance with talc and its high water content. Multiple structures containing loosely bound carbonate ions exist. The easily exchanged carbonates allow for applications of the mineral in wastewater treatment and nuclear fuel reprocess… WebAug 21, 2012 · Preparation of synthetic hydrotalcites (Mg/Al LDHs) Synthetic hydrotalcite (Mg 6 Al 2 (OH) 16 (CO 3)·4H 2 O) was prepared by the co-precipitation from chloride salts using the method previously described [36, 43].Co-precipitation involves the preparation of two solutions, one containing the divalent and trivalent cations which will eventually form …
