Selective adsorption of vitamin E from palm fatty acid distillate on silica-packed fixed-bed columns

Understanding the behavior of vitamin E adsorption during chromatographic separation was useful for a better control of the process. In this study, a pre-concentrated vitamin E fraction from palm fatty acid distillate (PFAD) was subjected to a normal phase silica-packed fixed-bed column for further...
