This product is a kind of alumina with special structure produced by special processing, which has property of non-toxic, tasteless, odorless, white fine sand-like, high chemical purity, decoloration effect, and rate fastsolution through. It has strong water absorption in air and the nature not change. It can be recovered after oven dry in 110℃.

The alumina is special developed for the decoloration in the production of antibiotic. Now it is mainly used for the domestic production of antibiotic such as cefotaxime sodium masonry, cefazolin sodium, cefradine, cephalosporin ground celery, etc. and alkaloids such as B12, Chinese notoginsenoside, Flavonoids, Rauwolfia, etc. Under the same test conditions, by comparing the results, it has the same performance in the indicators of refining decoloration effect, regeneration capacity, service lifetime, through rate, etc., and decoloration effect is even superior to imported products in some indicators. In addition, it is also widely used inchromatography and drying process.
