The Effect of Humic Acid on Phenanthrene Sorption in Kaolin Clay
Background & Objectives: Polycyclic aromatic hydrocarbons (PAHs) are considered as important organic contaminants due to their high toxicity and carcinogenic properties. Among PAHs, phenanthrene is found in most contaminated sites. Sorption and desorption of phenanthrene in soil affect the fate...

Student of Civil and Environmental Engineering, School of Civil Engineering, Iran University of Science and Technology, Tehran Professor., Department of Water and Environment, School of Civil Engineering, Iran University of Science and Technology, Tehran Assistant Prof., Department of Analytical Chemistry, School of Chemistry, Iran University of Science and Technology, Tehran Background & Objectives: Polycyclic aromatic hydrocarbons (PAHs) are considered as important organic contaminants due to their high toxicity and carcinogenic properties. Among PAHs, phenanthrene is found in most contaminated sites. Sorption and desorption of phenanthrene in soil affect the fate of the contaminant in soil-water system. Presence of organic matter (OM) in the soil matrix can also affect sorption and desorption of phenantherene. In this research, effect of soil organic matter on sorption of phenanthrene in kaolin soil was studied. Materials & Methods: The sorption of sorption of phenanthrene in kaolin clay was assessed in the presence and absence of organic matter. These two soil types were used in batch sorption experiments of Phenanthrene to determine the sorption properties. Results: It was found that organic matter increases the cation exchange capacity, water content, and pH of the soil. Sorption of phenantherene in both kaolin and OM-added kaolin was better fitted with Freundlich linear model. Moreover. soil organic matter increased phenanthrene sorption in soil. Conclusion: It was observed that with 41.04% increase in OM, distribution coefficient of phenanthrene sorption in soil increased by 36.69%.http://ijhe.tums.ac.ir/browse.php?a_code=A-10-605-1&slc_lang=en&sid=1Phenanthrene Organic Matters Sorption Soil Kaolin |
