In our previous work, we successfully prepared NaA zeolites through hydrothermal processes using chemosynthetic low silicon geopolymers [15-16]. Geopolymers are non-crystalline or quasi-crystalline gels with three-dimensional network structures that were first introduced by Joseph Davidovits in 1978 [17]. In general, geopolymers are prepared from natural minerals or solid wastes through the polymerization of silicon-oxygen tetrahedra and aluminum-oxygen tetrahedra [17-19]. However, in this work, the geopolymers were synthesized through the sol-gel method to overcome the disadvantage of using impure raw materials [20-21]. In this paper, we report the preparation and study of an Al2O3-2SiO2-Na2O geopolymer membrane transformed in situ into a self-supporting NaA zeolite membrane through a hydrothermal process. The preliminary results from the desalination of NaCl solutions using the self-supporting NaA membrane were also reported. In this paper, we first prepared inorganic membranes of an Al2O3-2SiO2-Na2O geopolymer through a gel casting process and then transformed the material into a NaA zeolite through a hydrothermal procedure. Hence, self-supporting zeolite membranes may be prepared through a hydrothermal synthesis procedure using a geopolymer gel according to the directions shown in Fig. 1. |

在我们以前的研究中，使用化学合成的低硅地质聚合物通过热液作用成功地制备了NaA沸石[15-16]。地质聚合物是具有三维网络结构的非晶性或准结晶性的凝胶，是由Joseph Davidovits在1978年首先提出的[17]。一般情况下地质聚合物是由天然的矿物或固体废物通过硅氧四面体和铝氧四面体的聚合反应制备的[17-1然而，在本研究中，为了克服使用不纯的原料的缺点，地质聚合物是通过溶胶-凝胶法合成的[20 - 21]。20-21]. 本文中报告了一种通过热液作用原位转换成自承NaA沸石膜板的Al2O3-2SiO2-Na2O地质聚合物膜板的制备和研究。还报告了使用自承NaA膜板进行NaCl溶液脱盐的初步结果。 本文中首先通过凝胶浇铸方法然后通过热液方法将这种材料转换成NaA沸石制备了Al2O3-2SiO2-Na2O地质聚合物的无机膜。综上所述，按照图1所示的指导，自承沸石膜板可以使用一种地质聚合物凝胶通过热液合成方法进行制备。 |
