Removal by Coagulation of Trace Organics From Mississippi River Water
In this study alum and ferric sulfate were evaluated for their effectiveness in removing four low‐molecular‐weight organic compounds—C14‐labeled octanoic acid, salicylic acid, phenol, and benzoic acid—from Mississippi River water and from water samples free of natural organic matter. Removal of these model organic compounds ranged between 3 and 20 percent, which is similar to the removals observed for the <1K fraction of natural organic matter. Solution pH affected the removal of the aromatic compounds but not of octanoic acid. Except for benzoic acid, all the model compounds were removed better in the absence of natural organics. Removal was found to be relatively insensitive to coagulant dosage.
