Abstract :

Environmental pollution, in particular contamination by PAHs is increasingly becoming a threat to humans and animals owing to their carcinogenic and mutagenic properties.. In this research an effort has been made to faicate litter and plant deis with nanometallic oxides generating a surface that can act as a better adsorbent for the removal of Phenanthrene (PAH), a common soil pollutant. Optimization of various parameters such as temperature, dosage, pH and time of the adsorbent was done by using response surface method. The result showed a significant increase in the PAH adsorption efficiency by doped surface. The maximum percentage adsorption of phenanthrene was 83.26% at 40�C and pH 7 by 8g of adsorbent at 8 hour of adsorption. Minimum % adsorption was 32.8% and average % adsorption was found to be 58.03%. The result presented in this study may aid in removal of phenanthrene and direct the bioremediation of environment in particular soil and sediments.
