Resumen:
In this work we report the results of a speciation study on the ternary complexes present in the systems formed by Ni(II) ion, 8-hydroxyquinoline (8-HQ) and the amino acids = α-alanine (HαAla), β-alanine (HβAla), phenylalanine (HPhe), proline (HPro), glycine (HGly), serine (HSer), threonine (HThr), aspartic acid (H 2Asp), glutamic acid (H 2Glu), methionine (HMet), histidine (H 2His) and cysteine (H 2Cys). The analysis involved the use of the potentiometric data with a least-squares program (LETAGROP) in aqueous 1M NaCl solution at 25° C. The binary complexes formed in the system Ni(II) - 8-HQ in aqueous 1M NaCl solution at 25° C were also determined and are presented here.
