Abstract: One of the many uses for activated carbons, which are incredibly adaptable adsorbents, is the bleaching of edible oils. Although wood, peat, lignite, and coal are the usual sources for activated carbon generation; agricultural wastes like nutshells are also taken into consideration as possible resources because of their renewable nature and abundance in Turkey. In this work, natural coal was used to make the activated carbon that was used to bleach the oil samples (Goya olive oil and palm oil). After the material has been dried, the experiment was conducted in a furnace that could be heated to 50000C.conduct adsorption on palm and soybean oils. Using a UV spectrophotometer with a wavelength of 460 nm, the absorbance and concentration of the two samples of neutralized oils were determined. Using the Langmuir isotherm equation, the equilibrium concentration, values for Ce/qc, b, and slopes for palm oil and soybean oil were determined. Ce/Qc = 1.Ce/Qo + 1/bQo, where Ce is the equilibrium concentration, Qc is the percent absorption, 1/Qo is the slope, Qo is the adsorption capacity, and b is the Langmuir constant.Therefore; activated coal was found to be moresuccessful at bleaching palm oil than goya olive oilin experimental trials, which led to this conclusion.
