| 摘 要： | 采用高温焙烧、盐酸浸渍和氯化铵浸渍等方法处理白庙子斜发沸石，并用化学分析、ＸＲＤ、ＩＲ和低温Ｎ２静态吸附等手段考察不同方法对沸石微孔结构的影响。实验发现，高温焙烧和盐酸室温浸渍使石微孔分布、微忆体积和比表面积减少；盐酸和氯化铵热浸渍能使沸石孔结构充分暴露，微孔分布、微孔体积和比表面积明显改善。讨论了微孔力场和孔道阳离子电场对对低压脱附滞后的影响。

| Abstract: | aimiaozi Clinoptilolite was treated by the calcination and the immersons with HCL ,NH_4Clsolutions. The effects of various treatments on its micropore structure were observed. The experi-ments showed that the calcination and the immerson with HCl solution at ambient temperature re-sulted in the decrease of micropore number,micropore volume and specific area, Also, they showedthat the heat immersons with HCl and NH_4Cl solutions resulted in fully appear of the microporestructure of the clinoptilolite and greatly increase in micropore volumes and specific areas.Thebeat immerson with NH_4Cl solution is better method for the research of the micropore structureof natural zeolite. |
