Jatropha curcas L. leaves was prepared as bio-sorbents and activated carbon for the purification of used cooking oil in reducing the value of FFA and PV. It compared the differences of the effect of functional group presence on bio-sorbents and pore frameworks on activated carbon can affect in decreasing of FFA and PV values of used cooking oil. XRD pattern and FTIR spectrum were observed the different of bio-sorbent and activated carbon properties of Jatropha curcas L. Leaves. The decrease in the lowest free fatty acid levels using bio-sorbent occurs at the optimum bio-sorbent mass of 8 g in 120 minutes with free fatty acid levels of 0.83% and activated carbon by 10 g in 150 minutes with free fatty acid levels is 0.79%. The optimum reduction of peroxide number using bio-sorbent is found in the mass of adsorbent 10 g for 150 minutes with a peroxide number is 9.87 mek O2 /kg and activated carbon is optimum in 10 grams for 90 minutes with a peroxide number is 13.99 mek O2 /kg. Bio-sorbent is more effective to reduce the PV value of used cooking oil while activated carbon have more potential to reduce its FFA value. © EM International.
