Abstract

Tocopherols are vital supplements with vitamin E activity necessary for inducing antioxidant and anti-inflammatory effects in vivo. This study aimed at using the concept of batch adsorption for the extraction of tocopherol from palm fatty acid distillate (PFAD). Silica gel as an adsorbent was characterized and modified to enhance its adsorptive performance. A comparative study between the untampered and the modified adsorbent samples emanating from morphological analysis, BET surface area evaluation, and FT-IR analysis demonstrated improved adsorption capabilities in the modified adsorbent sample. Adsorption equilibrium data were obtained from laboratory experiments.
