摘要
In this work, we present the results from a chemical speciation study of binary and ternary complexes formed by Ni(II) ion with picolinic acid and the amino acids = Arginine (HArg), Tryptophan (HTrp), Asparagine (HAsn), Glutamine (HGln), Lysine (HLys), Valine (HVal), Leucine (HLeu) and Isoleucine (HIle). The analysis is based on the use of potentiometric data analysed with the least-squares program LETAGROP in 1 M NaCl aqueous solution at 25 degrees C.
