KINETICS AND EQUILIBRIUM STUDIES OF COLOUR PIGMENTS REMOVAL FROM CRUDE PALM OIL USING ACID ACTIVATED KAOLIN CLAY
ABSTRACT The adsorptive removal of the colour pigment (due to high content of carotenoids) from palm oil using ortho-phosphoric acid activated kaolin clay was investigated in this research. The clay was activated at different acid concentrations to improve its adsorptive capacity. In order to study the effect of process variables on the bleaching efficiency of the raw and activated clay ...
