Abstract: In this study, the acid-base and chelate-forming properties of surface-active complexanes of the type of 2-alkyl-nitrilotriacetic acids have been investigated by the use of l H NMR spectroscopy, potentiometry, polarography, and paper electrophoresis. The values of dissociation constants and stability constants obtained for 25 bivalent and trivalent ions give evidence that the investigated substances preserve the chelate-forming properties of the original complexone NTA.
