SORPTION OF IONIC LIQUIDS

Ionic liquids (ILs) attract growing attention and the range of their potential application is constantly expanding. To meet not only the technological but also environmental requirements for their implementation to wide-scale use, we undertook an extensive literature study into ILs interaction and sorption onto soils. The available data were compared and subjected to critical review. We also performed sorption batch test of 1-methyl-3-octylimidazolium chloride in a broad concentration range onto low pH and forest soil poor in organic matter. The sorption isotherm closely matched the isotherm described previously in the literature as corresponding to double layer sorption. From the sorption isotherm we calculated the partition coefficients (K-d).
