Abstract

Effect of Tetrabutylammoniumbromide (TBAB) on the chemical speciation of binary complexes of Zinc(II) with L-glutamine and succinic acid has been studied pH metrically in varying concentrations (0.0-3.0 %, w/v) of TBAB-water mixtures. The temperature and the ionic strength maintained in the titrant are 0.16 mol dm-3 and 303 K, respectively. The possible models that represent the title systems are refined by using the computer programs SCPHD and MINIQUAD75. The models contain ML and MLH for succinic acid and ML2 and ML2H for L-glutamine complexes of Zinc(II). The variation of the stability constants with a dielectric constant is explained based on electrostatic and non-electrostatic forces. The species distribution with pH at different solvent compositions, corresponding chemical equilibria, and structures of the complex species are described.
