Speciation of the binary and ternary complexes of Copper(II) with 2-(benzo[d]thiazol-2-yl)nicotinic acid and some amino acids

In this work, we present the results from a chemical speciation study of binary and ternary complexes formed by Cu(II) with 2-(benzo[d]thiazol-2-yl)nicotinic acid (HL) and the amino acids: Aspartic acid (H(2)Asp, H2B), Glutamic acid (H(2)Glu, H2B), Histidine (HHis, HB), Serine (HSer, HB), Threonine (Thr, HB), Phenylalanine (HPhe, HB) and Methionine (HMet, HB). The analysis is based on the use of potentiometric data analysed with the least-squares programme LETAGROP in 1 M NaCl aqueous solution at 25 degrees C.

Automated summary

In this study, the results of a chemical speciation analysis of binary and ternary complexes formed by Cu(II) with 2-(benzo[d]thiazol-2-yl)nicotinic acid and various amino acids were presented. The analysis was conducted using potentiometric data and the least-squares program LETAGROP under specific conditions.
