Batch and column experiments to support heavy metals(Cu,Zn and Mn) in alluvial sediments

         

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,Glbasι,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.
