Adsorption mechanisms of pigments and free fatty acids in the discoloration of shea butter and palm oil by an acid-activated Cameroonian smectite
Discoloration mechanism of shea butter and palm oil was studied by the adsorption of pigments and free fatty acids onto a Cameroonian clay. Adsorbent characterization was performed using ICP-AES, FTIR, SEM, N2 gas adsorption and CEC. The adsorbent is a microporous swelling clay of smectite type. Dis...
