胺基功能修饰的介孔材料及其在钼铼分离中的应用

本发明涉及种胺基功能修饰的介孔材料及其在钼铼分离中的应用。采用的技术方案是：先将第部分NaSiO溶解于去离子水中，加入均三甲基苯与P123的混合溶液中，然后40℃下搅拌。反应定时间后，再将第二部分NaSiO溶解于去离子水中，加入上述溶液中，40℃搅拌6h，100℃老化24h，抽滤，洗涤，干燥后的产物放入马弗炉中，于550℃焙烧4h，得到产物SBA-15。将SBA-15置于三口瓶中，加入80mL乙醇溶液，氮气保护下加入定量的APTES搅拌30min，慢速滴加入20mL HO，搅拌30min，抽滤，110℃干燥24h，得产物。本发明方法简单、成本低、吸附量大、钼铼分离选择性好。 The invention relates to an amine-containing functional mesoporous material and application thereof to separation of rhenium and molybdenum. According to the technical scheme, the material is prepared by the following steps: dissolving a first part of Na2SiO3 in deionized water, adding to a mixing solution of mesitylene and P123, and stirring at 40 DEG C; reacting for a certain period of time, dissolving a second part of Na2SiO3 in deionized water, adding to the mixing solution, stirring at 40 DEG C for 6 hours, aging at 100 DEG C for 24 hours, performing suction filtration, washing and drying to obtain a product; roasting the dried product in a muffle furnace at 550 DEG C for 4 hours to obtain an SBA-15 product; and placin
