摘要：

Exchange reactions between Pb (II) and the alkaline-earth complexes of trans-l,2-diaminocyclohexane-N,N,N',N'-tetraacetate (CyDTA) proceed at sufficiently different velocities to permit the kinetic determination of mixtures of Mg, Ca, Sr, and Ba. The rate-determining step with each complex is its reaction with hydrogen ion. Ultraviolet absorbance of PbCyDTA2- is used to monitor the reaction but there is no kinetic dependence on Pb (II). Reaction rate constants are in the ratio of 1:6.5:96:1660forMg:Ca:Sr:Ba. The determinations are rapid and free of interference from other metal ions. © 1969, American Chemical Society.
