Conclusions
-
1.
The pH-meter titration method was used to study the complexing of Tl(III) with iminodiacetic, hydroethyliminodiacetic, and nitrilotriacetic acids in solution. It was shown that T1(III) can have a coordination number of 8 in complexonates.
-
2.
The values of the first and second acid dissociation constants of the hydroxyethyl protons of T1(III) bis(hydroxyethyliminodiacetate) were calculated.
