Collidine sorption on a silt loam soil and a spent shale

A laboratory study was made to assess the sorption of collidine on a Ritzville silt loam soil and a retorted oil shale from the Laramie Energy Research Center. Collidine sorption was found to fit a Langmuir isotherm type sorption on both the soil and spent shale systems. In the case of the soil, two Langmuir type equations were resolved from the data, though only a single equation was resolved from the retorted shale data. Langmuir sorption capacity and bonding term parameters were determined for both systems by linear regression analysis.
