Abstract

Introduction: Polycyclic Aromatic Hydrocarbons (PAHs) belong to one of the groups of persistent organic pollutants (POPs) which are the result of incomplete combustion of organic materials, volcanic eruptions and forest and agricultural fields’ fires in the environment. However, human factors are main source of these pollutions. Nowadays, these compounds are among the main concerns related to the pollutants which, can easily enter into the land and water systems. ABSORPTION of aromatic hydrocarbons and poly-aromatic molecules on the surfaces of carbon nano-tubes (CNTs) have increased in recent years. In this study, ABSORPTION of PHENANTHRENE (as a representative of aromatic hydrocarbons groups) on MULTI-WALLED CARBON NANO-TUBES was investigated in organic environment.Material and Method: All experiments were performed in a laboratory environment with a temperature of 24±2.Different variables including the type of solvent, solvent volume, pH of the environment, the ABSORPTION time of optimal PHENANTHRENE concentration, and the highest removal efficiency under optimized parameters were obtained. Samples were analyzed using HPLC.Result: Findings showed that methanol with the volume of 10 ml, and the ABSORPTION time of 1.5 hours and 1.3 ppm concentration had the maximum ABSORPTION efficiency. Environmental pH had no effect on the ABSORPTION efficiency.Conclusion: MULTI-WALLED CARBON NANO-TUBES have high ABSORPTION capacity for the ABSORPTION of PHENANTHRENE. Moreover, in an organic environment, the level of PHENANTHRENE ABSORPTION on multi-walled carbon nano-adsorbent was more than 90% and according to the material used was 92%. Day-to-day and within-day reproducibility confirmed the mentioned results.
