Conclusions
-
1.
New organophosphorus complexing agents were synthesized: ethylenediamino-N,N'-diethylphosphonic, N,N′-dimethylethylenediamino-N,N′-dimethylphosphonic, and N,N′-dimethylethylenediamino-N, N′-diethylphosphonic acids and also the iodomethylate of the last acid.
-
2.
The acid dissociation constants for these compounds and the stability constants for their complexes with nickel, copper, dysprosium, and uranyl ions were determined.
