A New Method for Data Analysis in Studies of Trace Metal Complexation

A new method for correction of asymptote at high additions of trace metal during titration was developed for van den Berg-Ružić plot. Using this method more accurate value for complexing capacity can be obtained from titration data. The accuracy of this parameter is a limiting factor for detailed study of trace metal complexation in natural waters. In addition, a sequential analysis of the shape of titration curves is proposed, by which more than two different groups of complexes can be identified in the case of a large ratio between the complexing capacity and trace metal concentration originally present in the water sample. These procedures are illustrated by the analysis of synthetic titration curves for two and three groups of different complexes. The complexation parameters were reproduced with satisfactory accuracy in both cases. Simultaneous use of both van den Berg-Ružić and Scatchard plots is suggested in other to test the agreement between the experimental titration data and theoretical predictions based on the complexation parameters determined.
