Coating of silica sand with goethite: preparation and …
The amount of iron in the pure silica sand (0.01% weight) is neg- ligible for our purposes. The experimental surface area of the goethite coated sand is well represented by the theoretical sum of the surface areas of the pure silica sand and the corresponding weight fraction of goethite (see Table 1 ). This fact demonstrates that …
