AB  - Ionic liquids are a form of organic or inorganic molten salts consisting positive 
      and negative ions. There have been several attempts of their utilization in 
      industry. These substances can be released from industrial sites into water and 
      soils thus causing contamination. The most significant chemical processes 
      affecting the behavior of ionic liquid cations in soils are related to their 
      transport. The major aim of this work was to investigate the transport process of 
      imidazolium ionic liquids in soils by column leaching experiments. Five types of 
      soil with varying total organic carbon (TOC) content (<0.1%, 0.5%, 4%, 9.9%, 
      44.8%), were utilized in the study of transportation of three ionic liquid 
      chlorides namely: 1-ethyl-3-methylimidazolium (EMIM), 
      1-n-butyl-3-methylimidazolium (BMIM), 1-n-hexyl-3-methylimidazolium (HMIM). The 
      results obtained indicated significant ability to immobilize ionic liquid cations 
      by soils with higher organic carbon content. The higher TOC value in soil results 
      in lower amounts of solutes migrating through the soil. Factorial regression has 
      been applied to modeling of the results. It relates soil and the ionic liquid 
      cation properties to the retardation of this cation in soil profile.
