The interaction of La(III), Gd(III), and Yb(III) with Tris((2,3-dihydroxybenzylamino)ethyl)amine) (TRENCAT) was investigated by means of potentiometric measurements in 0.1 mol dm(-3) aqueous solution of sodium perchlorate at 25 degreesC. The formation of complexes between the partially protonated ligand and lanthanides has been observed and the values of their formation constants are reported.

Abstract
The interaction of La(III), Gd(III), and Yb(III) with Tris((2,3-dihydroxybenzylamino)ethyl)amine) (TRENCAT) was investigated by means of potentiometric measurements in 0.1 mol dm(-3) aqueous solution of sodium perchlorate at 25 degreesC. The formation of complexes between the partially protonated ligand and lanthanides has been observed and the values of their formation constants are reported.
