Investigation of sorption of potential anthropogenic pollutants on oil shale and its composite forms
Sorption of three different asymmetric polar organic compounds – TEBA (benzyltriethylammonium chloride), Supragil WP (sodium diisopropyl naphthyl sulfonate) and 4-nitrophenol – was studied on Hungarian oil shale and its special composite forms. These frequently used and persistent chemicals can beco...

| Tartalmi kivonat: | Sorption of three different asymmetric polar organic compounds – TEBA (benzyltriethylammonium chloride), Supragil WP (sodium diisopropyl naphthyl sulfonate) and 4-nitrophenol – was studied on Hungarian oil shale and its special composite forms. These frequently used and persistent chemicals can become anthropogenic pollutants when they get into the environment. Sorption is an appropriate method to remove these chemicals by oil shale, but the difficulty of the usage of oil shale as a sorbent is its crumbling nature. Therefore two different types of composites (oil shale–alginate and oil shale–agar) were prepared, which are more manageable, and their sorption abilities were compared to the oil shale powder. The sorbed amount of Supragil WP and 4-nitrophenol on oil shale in the oil shale–alginate composite was higher than on powder, while the sorbed amount of TEBA on oil shale in the oil shale–agar composite was almost the same as on powder. |
