摘要
Laboratory batch sorption and column transport experiments were performed on heterogeneous alluvial soils with a wide range of physical characteristics from wells that are located in the region between Mogan Lake and Eymir Lake,Glbasι,Ankara.The mean values for the Kd of Cu were found to be highest in clay(32550.350 L/kg) and lowest in loamy sand(18170.76 L/kg).The minimum and maximum sorption capacity values(mean values) for Zn were found to be in clay(10985.148 mg/kg) and in silty loam(8597.14 mg/kg) units,respectively.Similarly,the minimum and maximum values for Mn were found in loamy sand(4908.695 mg/kg) and clay(7587.391 mg/kg) units.The non-linear least-squares optimization code "CXTFIT" was used to determine transport parameter values by curve-fitting.The results of the column experiments demonstrate dispersivity values within the range of 0.024-1.13 cm for soil samples.
