• Authors investigated the determination of small amounts of iron in several samples of rice bran oil and rape seed oil by spectrophotometry. <BR>The maximum absorption of aqueous of Fe<SUP>2</SUP>+-2, 4, 6-tripyridyl-sym-triazine complex is 595 mμ, and optical density of the solution at 595 mμ conforms to Beers low. <BR>Oil samples were obtained at each of the unit operations in the refinery. <BR>It was found that the range of content of iron in the several samples of rice bran oil and rape seed oil was 0.370.97 ppm and 0.290.98 ppm respectively, and the standard deviation of measured values was below 0.06. <BR>“Native” content of iron in rape seed oil was approximately 0.29 ppm. 47.3% of iron in refined rice bran oil was adsorbed by amberlite IR 120 resin column.
