dc.description.abstractSilica extraction from Palm Oil Mill Fly Ash (POMFA) using sodium hydroxide solvent was done at temperature above its boiling point in pressurized stainless steel extractor. The main composition of the POMFA was 39.99% silica and 40.83% unburned carbon. The response surface method (RSM) was applied to optimize the temperature and the stirring speed. The extract silica was analyzed using Inductively Plasma Optical Emission Spectroscopy (ICP-OES) to measure the silica content. At the optimum temperature and stirring speed the effect of the mass ratio NaOH to POMFA was studied. The optimum conditions were temperature of 156 oC, stirring speed of 461 RPM and mass ratio of NaOH to POMFA 0.02. The silica conversion at the optimum conditions was 76.44 ± 0.44 %.en_US
