Abstract The adsorption of pyridine from aqueous solutions onto the solids generated by the processing of Rundle oil shale shows that the adsorption isotherm is of Langmuir type (L-4) with two plateaux. Cations which are leached from the spent shale or which are in retort water (Na, K, Ca, NH4) have a marked effect on the adsorption; the anion effect, while measurable, is much less. The adsorption is controlled by a number of factors such as pyridine co-ordination, surface protonation and ion exchange. XRD studies show that the montmorillonite in the spent shale expands during the sorption process, indicating a re-orientation of the adsorbed pyridine. The results identify some of the mechanisms likely to control the transport and removal of N-heterocyclic compound in spent shale waste dumps.
