Examples from the Web for decolorization
Decolorization of gelatine sols may be effected by any substance with a large specific surface (see p. 201).
Further, decolorization by adsorption probably also involves the removal of the last traces of emulsified grease.
Most usually the decolorization and filtration processes are also conducted with such an acid sol.
As the liquors extracted are weaker, the extraction is more complete and the decolorization more easily effected.
