摘要
This paper describes the quantitative analysis and preparative isolation of sodium polycarboxylates in detergents by means of gel permeation chromatography. An analytical monitoring method separates the polymers from other low molecular detergent ingredients within 10 minutes. There is no separation of the various molecular weight polycarboxylate macromolecules themselves. They elute from the column as a single narrow peak at the exclusion volume. A second preparative gel filtration method allows isolation of polycarboxylates in amounts necessary for further characterization. Appropriate sample pretreatments and possible interferences are discussed.
