PITZER AND THERMODYNAMIC PARAMETERS OF TRIETHANOLAMINE AND GLYCINE INAQUEOUS SALINE SOLUTIONS

On the basis of the ionic strength dependence of the equilibrium const ant (pK) of triethanolamine (TEA) and glycine, the ionic interaction parameters of the species involved in the equilibria TEAH+ double-line arrow pointing left and right TEA + H+ (for TEA), AH2+ double-line ar row pointing left and right AH + H+ and AH double-line arrow pointing left and right A- + H+ (for glycine) in aqueous solutions of KCl and K NO3, respectively, were determined using the Pitzer equations. Values of pK were expressed on both the molarity and the molality scale at v arious temperatures and values of thermodynamic quantities DELTAG0, DE LTAH0 and DELTAS0 ascertained, for TEA.
