SUMMARY
Silica is one of the inorganic solids that has a high degree of stability and specific surface area. The raw materials in the manufacture of silica can be obtained from biomass such as oil palm ash boiler. The extraction of silica from the ash of palm oil boiler ash by sol gel method aims to obtain high levels of silica purity and high yield, and know the characteristics. Silica was extracted from ash oil palm boiler using NaOH solvent variation (1 M, 3 M and 5 M) and then 3M HCl is reacted with synthetic sodium silicate from ash oil palm boiler to form gel with a pH of 7. The formed gel was allowed to stand for 48 hours. Then washed with aqua DM and dried in an oven at 105 oC for 2 hours. Silica was characterized by FTIR, XRD, XRF and BET surface areas. The result of silica extraction showed that the silica reacted with a concentration of NaOH 1 M, 3 M, and 5 M contained an -OH functional group of Si-OH and Si-O (Si-O-Si). XRD results for silica with a 1 M NaOH concentration showed a widening pattern of approxismately 2ϴ = 26.5211o. At 3 M and 5 M NaOH concentrations showed there were some highest peaks of 2ϴ = 45.5165o and 2ϴ = 31.7028o. The XRF results in the silica treated with 1 M, 3 M, and 5 M NaOH were 77.032 %, 74.969 %, and 71.45 % respectively with a surface area (BET) of 110.693 m2/g, 82.622 m2/g and 67.525 m2/g.
