摘要
用化学分析、Ｘ射线粉晶衍射及扫描电子显微镜等方法，研究了铁型斜发沸石（简称为ＦｅＣｐ）的热稳定性及其对可溶性硫化物和碳酸盐的复合作用。研究结果表明：ＦｅＣｐ在５００℃加热处理可转变为沸石质准玻璃；ＦｅＣｐ及其准玻璃的复合作用包括固体样品内部的包盐作用及表面的连生结晶作用，其上复合的阴离子具有可置换性。ＦｅＣｐ的复合性能具有潜在应用价值。
Thermal stability of Feclinoptilolite(FeCp)and its complexing action for soluble sulfides and carbonates were studied by means of chemical analysis,Xray diffraction and scanning electron micrograph.The results show that FeCp is transformed to the zeolitic metaglass by heating at 500℃;the complexing action of FeCp and its metaglass includes the salts occlusion inside zeolitic structure and the “connecting growth”crystallization on the surface.Compounded anions are replaceable property.This complexing property is expected to have potential application value.
