| Abstract: | | 1. |
A new organophosphorus complexing agent, N,N -di-(2-hydroxyethyl)ethylenediaminodimethylphosphonic acid was synthesized, which contains additional functional hydroxyl groups in the alkyl radicals on the nitrogen atoms.
| | 2. |
The acid and complex-forming properties for this complexing agent were studied. The composition was studied for the complexes using the methods of spectrophotometry, and high-frequency titration.
