Abstract:
This study examined the adsolubilization of two organic contaminants, styrene and
pyrene, commonly found in soil and groundwater, using a fixed-bed column adsorption
process with rhamnolipid-modified alumina. Rhamnolipid biosurfactants produced by
Pseudomonas strains were selected to use in this work. In the past research, rhamnolipids
were demonstrated to enhance the removal efficiency of oil spills, PAHs, diesel, and heavy
metals from contaminated soil and groundwater. The fixed-bed experiment was conducted
through a sequential analysis involving tracer studies, surfactant adsorption, and the
adsolubilization of organic solutes. The desorption study was also used to determine
regeneration capability by distilled water. The primary objectives were to assess the
effects of varying organic feeding flow rates, as indicated by the retardation factor and
adsolubilization capacity. Results indicated that rhamnolipid significantly enhances the
adsolubilization capacity of organic solutes in the column, particularly increasing the
retardation rate at lower feed flow rates. Additionally, the molecular weight of organic
solutes affects their polarity, which in turn influences their behavior during
adsolubilization. As a result, styrene and pyrene are solubilized in different regions of
the surfactant admicelle. Styrene, with its lower molecular weight and greater water
solubility, is located in the palisade region, while pyrene is found in the core area,
representing the higher polar region of the admicelle structure
