Between 2004 and 2006, researchers discovered several contaminants in refined vegetable oils, including palm oil. Glycidyl esters (GE) and 3-monochloropropane-1.2-diol esters (3-MCPDE) are found in Refined Bleached Deodorized Palm Oil (RBDPO) as products formed during purification of Crude Palm Oil (CPO). These contaminants have carcinogenic properties and need to be purged out of palm oil. This research focuses on the modification of natural zeolite adsorbents to be utilized in expunging 3-MCPD and Glycidyl Esters on RBDPO from palm oil. Natural zeolite adsorbent is activated by acid and ion-exchange. Then, characterization of adsorbent is conducted using BET method to determine the surface area of the adsorbent. To analyze adsorption capacity, reaction properties, and type of adsorption, experimental data from several sources are modeled. Experimental data from Cheng, et al. (2017), Strijowski, et al. (2011), and Adam and Beri (2019) are chosen in this study. Activation of zeolite with 0.1M hydrochloric acid produced a surface area of 79.534 m2/g, a total pore volume of 0.1398 cm3/g, and a pore diameter of 70.3 Å. Activation of zeolite with 1M hydrochloric acid produced a surface area of 88,238 m2/g, a total pore volume of 0.1247 cm3/g, and a pore diameter of 56.53 Å. Activation of zeolite with 1M hydrochloric acid followed by Mg ion-exchange resulted in a surface area of 26.237 m2/g, a total pore volume of 0.1239 cm3/g, and a pore diameter of 188.87 Å. OPAC has a maximum glycidyl ester adsorption capacity of 37.03 mg/g at 30?, 34.41 mg/g at 40?, 32.62 m /g at 50?, and 27.35 mg/g at 60?. GE adsorption with OPAC is exothermic and classified as physical adsorption. Adsorption of 3-MCPDE with activated carbon has a minimum adsorption capacity of 30.82 mg/g at 1200 rpm and 45 mg/g at 800 rpm. Adsorption of 3-MCPDE with activated carbon is exothermic and classified as physical adsorption
