Title

Chemical Speciation of ternary Complexes of L -Phenylalanine and Maleic Acid under mimicked physiological condition; Potentiometric studies.

Abstract

Abstract Chemical speciation of ternary complexes of Co (II), Ni (II) and Cu (II) ions with L- Phenylalanine and Maleic acid was studied pH metrically in the concentration range of 0–50 % v/v DMF-water mixture maintaining an ionic strength of 0.16 mol L-1 at 303.0 K. Alkali metric titrations were carried out in different relative concentrations (M: L: X = 1:2.5:2.5, 1:2.5:5.0, 1:5.0:2.5) of metal (M) to phenylalanine (L) to maleic acid (X). Stability constants of ternary complexes were calculated and various models were refined with MINIQUAD75. The derived ‘best fit’ chemical speciation models are based on crystallographic R-factors, χ2 and Skewness and Kurtosis factors. The species detected are MLXH, MLX and ML2X for Co (II), Ni (II) and Cu (II) in DMF water mixture. The chemical speciation, metal bioavailability and transportation were explained based on the stability constants.
