Abstract
Zn/Al LDHs were successfully prepared with ion exchange resin and mixed hydroxides, and the effects of different pH were studied. The results evidenced that the products with lamellar and layered structures could all be obtained at different pH. When pH was around 10.9, Zn6Al2(OH)16CO3·4H2O with hexagonal lamellar, complete crystal structure, high crystallinity, and certain purity could be obtained. The adsorption experiment indicated that LDHs prepared after multiple cycles of resin still had a good adsorptivity for MO. Due to the unique internal structure and ion-exchange capacity of resin, the products had good dispersion and nano-scale, and could be directly applied.
