PEMANFAATAN LEMPUNG MAREDAN SEBAGAI ADSORBEN PEROKSIDA DARI CRUDE PALM OIL : VARIASI BERAT ADSORBEN DAN SUHU

Abstract

Maredan clay has been used as an adsorbent for adsorption of peroxide from CPO. For this purpose, clay Maredan was activated using the H2SO4 with concentration variation of 0.1; 0.2 and 0.3 M, followed by physical activation by calcination at a temperature of 500oC for 10 hours. Modified clay was used as an adsorption medium of peroxide from CPO. Weight parameters of adsorbent observed in the adsorption process were 0.5; 1.0 and 1.5 g and temperature variation were 60°C and 80°C. The highest adsorption activity was shown in the adsorption treatment with the adsorbent 1,5 g by weight of clay Maredan 0.2 M H2SO4 activated at a temperature of 60oC adsorption. The results showed a decrease in peroxide value of 18.72%.
