Determination of Aromatic Hydrocarbons in Biologically Treated Water from a Coal Gasification Process

Source

A high-performance liquid chromatography gradient scheme has been used to separate the aromatic hydrocarbons in the aqueous effluents of a coal gasification process. Samples of raw water, activated sludge, and activated sludge plus carbon-treated effluents were evaluated. By using a simple chromatographic concentration step before separation, the detection of aromatics below the parts-per-million level can be done routinely. Employing multiple detectors aids in peak identification.

The use of activated sludge plus activated charcoal was highly effective in removing aromatic hydrocarbons from the aqueous effluent of this gasifer. The final treated effluent contained some hydroxy-substituted multiring aromatics that were not removed by these treatments.
