The Utilization of Jatropha curcas L Leaf as Adsorbent for Purification Used Cooking Oil

Abstract

The reused of cooking oil had been widely found in Indonesia whereas it is dangerous for health due to its carcinogenic properties. Purification of used cooking oil had been extensively investigated using various methods such as adsorption. Carbon-based materials are the common adsorbent cause having large capability to adsorb organic and inorganic compound. Activating the carbon surface affected the higher pores and adsorption potential. Recently, some raw organic materials are converted to activated carbon. In this investigation, we transformed Jatrhopa curcas L leaves to activated carbon for purification the used cooking oil. The resulting of the purification of used cooking oil were investigated based on the free fatty acid and peroxide value under adsorbent optimum condition.
