无模板剂条件下,采用水热体系合成出A/X复合沸石。用XRD粉末衍射法研究了原料配比(硅铝比、水钠比及钠硅比,均为摩尔比)对合成A/X复合沸石的影响,表明A/X复合沸石在较窄范围内生成。TEM照片显示合成样品晶粒均匀,粒度约为200 nm。A/X复合沸石的钙离子交换值达到与4A沸石同水平,镁离子交换值远远高于4A沸石,且随X型沸石质量分数的升高而增大。 No template agent conditions, the use of hydrothermal system synthesis A / X composite zeolite. XRD powder diffraction method was used to study the effect of the raw material ratio (Si / Al ratio, sodium to sodium ratio and sodium to silica ratio, both molar ratio) on the synthesis of A / X composite zeolite, indicating that the A / X composite zeolite was formed in a narrower range . TEM photographs show that the synthesized samples have uniform grain size of about 200 nm. A / X composite zeolite calcium ion exchange value reached the same level with 4A zeolite, magnesium ion exchange value is much higher than 4A zeolite, and with the X-type zeolite mass fraction increases.
