Silica gel adsorbents doped with Al, Ti, and Co ions improved adsorption capacity, thermal stability and aging resistance

The metal ion doped silica gel adsorbents based on ceramic fiber were prepared by impregnation coprecipitation method. The effects of the concentration and the acidity of impregnation salt (cobalt, aluminum or titanium sulfate) solution on the adsorption capacity of the modified silica gels were inv...
