  • Published 1998 in Journal of colloid and interface science


Carbon-silica composite adsorbents with high surface area and pore volume were prepared from natural elutrilithe. The elutrilithe was chemically activated with K2CO3 at 1123 K and then dissolved in water. The textural and adsorptive properties of the composite adsorbents can be adjusted by varying the pH and concentration of the sol mixture and the gel… (More)
