Abstract
With the constant development of new ionic liquids, the understanding of the chemical fate of these compounds also needs to be updated. To this effect, in this contribution, the interaction of a number of novel ionic liquids with soils was determined. Therefore, three novel headgroups (ammonium, phosphonium or pyrrolidinium) with single or quaternary substitution were tested on a variety of soils with high to low organic matter content, and high to low cation exchange capacity, thereby trying to capture the full range of possible soil interactions. It was found that the ionic liquids with single butyl alkyl chains interacted more strongly with the soils (especially with a higher CEC), at lower concentrations, than the quad substituted ionic liquids. However, the quad substituted ionic liquids interacted stronger at higher concentrations, due to the double layer formation, and the stronger induced dipole interaction with previously sorbed molecules.
