沸石是一种碱或碱土金属离子的含水铝硅酸盐。是架状构造细微结晶质矿物,结构中充满了不同大小孔径的空腔和孔道,具有较大的开放性和很大的内表面积。在沸石的晶穴和孔道中有可交换的碱或碱土金属阳离子和中性水分子。这些水可以脱附自由而不改变沸石的结构,称为 Zeolites are hydrous aluminosilicates of alkali or alkaline earth metal ions. Is a frame-like structure of fine crystalline minerals, the structure is filled with different size pores and pores, with a larger openness and a large inner surface area. There are exchangeable alkali or alkaline earth metal cations and neutral water molecules in the crystal lattices and pores of the zeolite. These water can be desorbed freely without changing the structure of the zeolite, called
