Abstract：
 The preparation method for macroporous high specific surface area alumina to overcome the problems that process is complex, can not satisfy to both side of macropore and high specific surface area comprises: adding basic solution precipitant into mixed liquid contained aluminum salt and cyclodextrin, obtaining deposition; cleaning, drying, and hot calcining. The product has specific surface area in 220~480m2/g and pore volume in 0.7~1.55ml/g, and can be used in drug and other indus..
