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. |

在我們以前的研究中,使用化學(xué)合成的低硅地質(zhì)聚合物通過熱液作用成功地制備了NaA沸石[15-16]。地質(zhì)聚合物是具有三維網(wǎng)絡(luò)結(jié)構(gòu)的非晶性或準(zhǔn)結(jié)晶性的凝膠,是由Joseph Davidovits在1978年首先提出的[17]。一般情況下地質(zhì)聚合物是由天然的礦物或固體廢物通過硅氧四面體和鋁氧四面體的聚合反應(yīng)制備的[17-1然而,在本研究中,為了克服使用不純的原料的缺點(diǎn),地質(zhì)聚合物是通過溶膠-凝膠法合成的[20 - 21]。20-21]. 本文中報(bào)告了一種通過熱液作用原位轉(zhuǎn)換成自承NaA沸石膜板的Al2O3-2SiO2-Na2O地質(zhì)聚合物膜板的制備和研究。還報(bào)告了使用自承NaA膜板進(jìn)行NaCl溶液脫鹽的初步結(jié)果。 本文中首先通過凝膠澆鑄方法然后通過熱液方法將這種材料轉(zhuǎn)換成NaA沸石制備了Al2O3-2SiO2-Na2O地質(zhì)聚合物的無機(jī)膜。綜上所述,按照?qǐng)D1所示的指導(dǎo),自承沸石膜板可以使用一種地質(zhì)聚合物凝膠通過熱液合成方法進(jìn)行制備。 |
