بررسي حذف آلاينده ي فنانترن از خاك هاي آلوده به PAHS به روش گياه پالايي

The study of the removal of phenanthrene polluter from PAHS contaminated soils with phy toremediation method

The Removal of Phenanthrene from polluted soils as a function of time and concentration is investigated . The results were based on a 16 week period and a greenhouse study for determining the removal rate of Phenanthrene by a grass , Sorghum vulgare Pers sudanense, in soils containing 10,15,20 ppm Phenanthrene. Variations in pollutant concentration was investigated by HPLC in different times. It was indicated that after five weeks of plant growth and developing its root system , there was a significant difference for planted soils versus implanted control soils (p<0.05). The elimination rate in planted treatment was 20% more than unplanted controls.
