The accumulation of toxic heavy metals in the food chain is one of the main detrimental abnormalities to personal and environmental health. Phenolic compounds, which are widely used today in various sectors of the industry, are one of these water and soil pollutants. The subject of this study is the experimental study of the function of cumin and its ashes in removing contaminated pollutants from phenolic compounds in which after preparing the acetophenol solution, the parameters affecting the yield of the cumin plant as a phenol absorber, such as pH, the ratio of the adsorbent to the Phenol solution, contact time and the initial concentration of phenol have been investigated. All measurements were performed in the presence of 4-amino-antipyrene and potassium fercyanide, by the white gold spectroscopy. The effects of removing phenolic pollutants from water were also investigated in four separate tests on fruits, roots and ashes of these two in the optimal conditions for each of these cases. The presented results, on average, reflect the results of all tests repeated three times and based on the results, the cumin plant in the initial concentration of phenol 150 mg / l, with the pH = 8 and contact time of 120 minutes exhibited the highest absorption efficiency with the adsorbent value of 0.8 g. While the best absorption efficiency for its ash, obtained at a primary concentration of phenol 200 mg / l and pH = 6 during the 120 minute contact time resulted in the presence of 11g adsorbent.
