Full Description

Gel permeation chromatography (GPC) and ultrafiltration (UF), both relatively inexpensive analytical techniques requiring moderate levels of analyst expertise, are potential tools for monitoring the presence of aquatic organic matter and humic substances in raw water sources as well as the removal of organic constituents during water treatment. The two methods provided somewhat different trends in the relative molecular weight distribution of dissolved organic matter in various water sources. The GPC method generally indicated a higher molecular weight than the UF method for a given source. Moreover, the GPC method was found to be more significantly affected by pH conditions. Includes 26 references, tables, figures.
