Mechanism of palm oil bleaching by montmorillonite clay activated at various acid concentrations

摘要: The mechanism of bleaching by a nonswelling montmorillonite clay activated at various acid concentrations was studied in the palm oil. Montmorillonite 2 parts H2SO4 10-40%. Chemical composition, ability, specific surface area and phosphorus content were studied. study showed that an initial increase ability increasing addition due to leaching organic matter impurities clay. consequence this case tends expose active sites for adsorption. Acid also removed Al3+, causing charge deficiency lattice and, hence, promoting adsorption properties A drop efficiency higher additions observed. This exces-sive collapse struc-ture.
