Abstract A method involving the use of paper ionophoresis is described for the study of equilibria in mixed - ligand complex systems in solution. The technique is based on the movement of a spot of metal ion under an electric field with the complexants added to the background electrolyte at pH 8.5. The stability constants of the complexes Pb(II) - nitrilotriacetate - cysteine and UO2(II) - nitrilotriacetate - cysteine are found to be 5.35 +/- 0.02 and 6.27 +/- 0.07 (logarithm of stability constant values) at ionic strength 0.1 M and a temperature of 35 degrees C.
