Selected properties of oil palm empty fruit bunch, EFB, and modified EFB were studied in order to prepare EFB for Alkaline peroxide mechanical pulping, APMP. The EFB surface was first desilicated - mechanically without washing, mechanically with subsequent washing and mechanically with subsequent washing and demineralisation, yielding EFB-1, EFB-2 and EFB-3, respectively. For treatment leading to EFB-3 84% silica was removable, apparently by dislodging the silica at metal-localised areas. EFB-2 was examined for its responses to soaking in both mild sodium hydroxide and water Ultraviolet-visible spectrophotometric analysis of the spent liquor revealed complementary results to spectrophotocolorimetry of the treated EFB-2 in terms of changes in the chromophoric behaviour.
