Abstract Retardation parameters (Rf) for sulfolane and thioalne were estimated using reference values and experimentally as they were mainly observed at an aquifer underneath a waste disposal site near Brisbane, Australia. Three soil aquifer materials e.g. clay, silty clay and sand were used as sorbents. At first, Rf was obtained employing Koc–Kow and solubility parameter, respectively, while experimental coefficients were determined from both batch and flow-through column tests. Additionally, Rf was observed at a single- and bi-solute system through the column test. There was not found any significant difference in Rf between Koc–Kow and solubility parameters, but the retardation coefficient was significantly dependent on organic carbon content for solubility parameter. In contrast, using Koc–Kow, the coefficient correspondingly varied with an amount of clay content contained in each soil. In the same manner, the batch-determined parameters were more subject to clay content. On the other hand, the column-determined parameters can be comparable with the desk-derived values. In a bi-solute system, they did not influence each other concerning retardation coefficients while they flew though the column simultaneously. It was concluded that there was a large discrepancy in retardation coefficient of batch- against both reference-oriented estimation and column-determined values.
