“…It can be a determining factor in the interaction between silica and the carboxyl groups of fatty acids, thus affecting the affinity and adsorption capacity of silica for FFA. The enhancement The illustration of the interaction between SiO 2 with FFA in porosity will give more space that contained in the adsorbent, so that more adsorbates will be adsorbed [35].…”

“…Based on Fig. 6, it can be seen that the best reduction occurred at an adsorbent mass of 0.24 g. The increase in the adsorbent dosage indicates a larger surface area and abundance of active sites available to interact with FFA molecules [35]. When the adsorbent dosage was below the optimum value, the removal of FFA was low because of the lower binding sites available for adsorption [36].…”

The synthesis of mesoporous material by utilizing palm oil boiler ash (POBA) waste as the silica source and methyl ester sulfonate (MES) surfactant as the template for a high-porosity was investigated for free fatty acids (FFA) adsorption. The research was initiated with silica extraction from POBA by sodium hydroxide addition through the sol-gel precipitation method. Silica modification was carried out with MES surfactant and 3-aminopropyltrimethoxysilane (APTMS) as the co-structure-directing agent (CSDA) in different calcination temperatures. Mesoporous silica-POBA (MS-POBA) free template had a surface area, pore diameter, and pore volume (41.033 m2/g, 4.180 nm, and 0.250 cm3/g) lower than MS-POBA with the template (71.0147 m2/g, 7.923 nm, and 0.524 cm3/g). The ability of MS-POBA to adsorb FFA reached its optimum conditions with an adsorption time of 20 min and an adsorbent dosage of 0.24 g. The FFA removal by MS-POBA with the template was found to have higher adsorption ability, which was 35.54%, compared to the MS-POBA free template of 26.68%. The high porosity of MS-POBA with a template makes the FFA adsorption capacity of this material higher than MS-POBA free template.
