    • PURPOSE: A purification method of zinc polluted soil using a solvent extraction and a system thereof are provided to improve the zinc removal efficiency out of the zinc polluted soil and to prevent the second environmental contamination as an extraction agent is able to be recycled. CONSTITUTION: A purification method of zinc polluted soil comprises a step of mixing an extracting solution in which D2EHPA(Di-2-ethylhexylphosphoric acid) is dissolved in water, to zinc polluted soil. The zinc concentration of the zinc polluted soil is 1000-5000 mg/kg. The mixing ratio of the extracting solution to the zinc polluted soil is a weight ratio of 1:1. In case the zinc concentration in the zinc polluted soil is less than 1500 mg/kg, the extracting solution and the zinc polluted soil are reacted for 0.5-0.6 hours in a first stage extractor to extract zinc from the polluted soil and separate purified soil simultaneously. In case the zinc concentration in the zinc polluted soil is more than 1500 mg/kg and under 4000 mg/kg, the extracting solution is supplied to a second stage extractor and reacted with the polluted soil in which zinc is firstly extracted in the first stage extractor, for 0.5-0.6 hours to separate purified soil by re-extracting zinc from the polluted soil and to send the extracting solution used in the second stage extractor to the first stage extractor again in order to be recycled. In case the zinc concentration in the zinc polluted soil is more than 4000 mg/kg and under 5000 mg/kg, the extracting solution is supplied to a third stage extractor and reacted with the polluted soil in which zinc is firstly and secondly extracted in the first and second stage extractors, for 0.5-0.6 hours to separate purified soil by re-extracting zinc from the polluted soil and to send the extracting solution used in the third stage extractor to the second and first stage extractors consecutively in order to be recycled.
