Artificially contaminated soil, with mixture of Co(II) and Sr(II) ions in different proportions, was tested. The main aim was to investigate the possibility of ethylenediaminetetraacetic acid (EDTA) utilization in the chemical extraction process as a method for soil remediation in the case of mixed contamination. The efficiency of this process when EDTA of 5?10-4 molL-1 was used was low, while the application of the EDTA solution of the initial concentration 5?10-3 molL-1 or higher showed almost the same efficiency. This suggested that the application of the solution EDTA (5?10-3 molL-1) is optimal from the aspect of cost and degradation of soil properties. Furthermore, process kinetic was fitted using one parameter shrinking core models. Kinetic data modeling showed that the process is complex, demanding multi resistance kinetic model.
