Methods for the detection of polar organophosphonates like the herbicide glyphosate
and its metabolite aminomethylphosphonic acid (AMPA) in seawater were developed within
this thesis. These compounds are difficult to measure in saltwater because salt matrix
ions hamper their enrichment and instrumental analysis. Matrix effects were successfully
reduced through sample desalination with electrodialysis. Moreover, glyphosate and
AMPA could be enriched from seawater with a salt-insensitive molecularly imprinted
polymer. This approach enabled the first detection of glyphosate and AMPA in seawater.

Methoden zur Messung von polaren Organophosphonaten wie dem Herbizid Glyphosat und
dessen Metabolit Aminomethylphosphonsäure (AMPA) wurden in dieser Arbeit entwickelt.
Diese Substanzen sind schwer in Salzwasser zu bestimmen, da Salzmatrixionen die Analyse
behindern. Probenentsalzung mittels Elektrodialyse wurde erfolgreich zur Reduktion
von Matrixeffekten eingesetzt. Darüber hinaus konnten Glyphosat und AMPA mit einem
matrix-unempfindlichen molekular geprägten Polymer aus Meerwasser angereichert werden.
Dieser Ansatz ermöglichte den ersten Nachweis von Glyphosat und AMPA in Meerwasser.
