Abstract
- The chemical speciation of binary and ternary VO2+-picolinic acid (HPic) complexes with the amino acids: Leucine (Leu, HL), Isoleucine (Ile, HL), Valine (Val, HL), Tryptophan (Thr, HL), Glutamine (Gln, HL), Lysine (Lys, HL), Arginine (Arg, HL) and Tyrosine (Tyr, H2L) were obtained. This study was performed by potentiometric titrations at 25 °C using 1.0 mol·dm−3 NaCl as the ionic medium. The experimental data were analyzed with the least squares program LETAGROP, and the respective distribution diagrams were obtained with the HYSS program. The relative stability parameters Δlog10K, log10X and %R.S were determined. [ABSTRACT FROM AUTHOR]
