The solid surperacid SO42-/TiO2-Fe2O3 was prepared by the method of coprecipitation and wet impregnation.

Using cobalt salt,aluminum salt or titanium salt as modifying agent,the metallic ion doped silica gel adsorbents based on ceramic fiber are prepared by treating ceramic fiber paper with impregnation coprecipitation of water glass and aqueous solution of acidic metallic-salt sequentially.

Three methods for preparing hydrotreating catalysts, such as dry mixing (DM), dry mixing followed by impregnation (DM I) and co impregnation (CI), were compared.

A novel kind of guided tissue regeneration (GTR) barrier membrane was fabricated using an immersion-precipitation phase inversion technique with the biodegradable material of chitosan.
