Bleaching with alternative layered minerals: A comparison with acid-activated montmorillonite for bleaching soybean oil

摘要: An extensive series of layered minerals including montmorillonite was studied to determine if the fundamental physicochemical properties responsible for pigment adsorption could be identified. Samples were subjected a uniform preparation regimen eliminate such secondary effects as particle size, moisture content, level activation and degree washing. By doing so, it has been possible show that both carotene chlorophyll adsorptions can described by rather simple model employs surface acidity pore volume key variables. Further, found this provides an adequate fit actual data only when specific regions these variables are considered (i.e., concentration sites strong acidity, not just total acidity; in region 50\s-200 A, volume).
