Adsorption and Desorption Carotenoids of Raw Palm Oil (Crude Palm Oil/CPO) using Salt M-Polystyrene Sulfonate (M = Na, Mg, Ca, Sr and Ba)

Abstract

Adsorption and desorption of carotenoids from crude palm oil (CPO) has been performed in ethanol, using five types of adsorbents M-Polystyrene Sulfonate or M-PSS ( M = Na, Mg, Ca, Sr, and Ba ) which is Sulfonate salts. NaPSS first adsorbents is made by neutralizing a solution of polystyrene sulfonic acid with acetyl sulfate. Four other M-PSS adsorbents are made from a reaction between Na-PSS with each salt MgCl2 , CaCl2 , SrCl2 and BaCl2 . The five adsorbents are characterized by Melting Point Apparatus (MPA), Spectrophotometry Atomic Absorption (SAA), Transform Infra Red Spectrometer (TIRS), Scanning Electron Microscope (SEM), Surface Area Analyzer with Brunauer Emmet Teller (BET) and Transmission Electron Microscope (TEM). The treatment resulted in the adsorption 100%, desorption 78.75% and the carotenoids recovered 78.75%.
