Abstract:
The present invention is directed to a separation medium comprising rotary dried or spray dried precipitated silica. The silica has a pore surface area P wherein log10 P>2.2, and the ratio of BET to CTAB is at least 1.0 measured prior to any surface modification of the silica.The present invention is further directed to a method of separating suspended or dissolved materials from a fluid stream, comprising contacting the stream with the separation medium described above.
