Removal of selected NSAIDs (nonsteroidal anti-inflammatory drugs) in aqueous samples by Octolig®
The possibility of removing representative nonsteroidal anti-inflammatory drugs (NSAIDs) from water was tested using Octolig®, a commercially available material with polyethylenediimine moieties covalently attached to high-surface area silica gel. The effectiveness of removal should depend on selected NSAIDs having appropriate anionic functional groups. NSAIDs selected had aromatic carboxylic groups: diclofenac, fenoprofen, indomethacin, ketoprofen, mefenamic acid, naproxen, and sulindac. These substances in deionized (DI) water were removed by passage over Octolig columns with removal values approaching 90% at environmental pH values, e.g., ca pH 6. Fenoprofen, however, was only removed to an extent of 80% in DI water and 62% in well water, presumably a result of competition with bicarbonate ions.
