Synthesis of Potassium Ion Sieve Membrane by Secondary Growth Method
Abstract:
potassium ionic sieve membrane was synthesized employing the secondary hydrothermal synthesis using tetrabutyl ammonium bromide as templates on the porous α-Al2O3 support.The zeolite membrane were characterized by XRD and SEM. The results show that the prepared membranes is potassium ionic sieve membrane, dense and continuous membrane could be obtained after crystallization synthesis was carried out at 423K for 12h and for three times.
