A potentiometric study on the complexes of His, Gly-His, ALa-His, Gly-Gly and Gly-Gly-Gly with Zn（Ⅱ）and Cd（Ⅱ）has been reported.Small-scale potentiometric titrations were carried out to determine stabil ity constants of complexes at 25℃ with I=0.10 mol dm^-3（KNO₃）.The computer programs SUPERQUAD were applied for data treatment with satisfactory results.
