Complexes of Pb(II), Cd(II) and Hg(II) with L-phenylalanine in the presence of non-ionic surfactants, at an ionic strength of 0.16 mol dm⁻³ and temperature 303 K are investigated pH-metrically. The existence of different binary complex species is established from modelling studies using the computer program MINIQUAD75. The increased stability of the complexes with increasing micellar content is explained by electrostatic forces. The influence of the micelles on the chemical speciation is discussed based on the mole fraction of the medium. Distribution diagrams of various species of the complexes in relation to pH are presented.
