Abstract
A method is proposed for the conductometric titration of lanthanoids i n unbuffered aqueous solutions based on the complexation reaction of t he cations with EDTA. The particular experimental conditions employed make it possible for such titrations to be performed at concentration levels as low as 1 muM. The accuracy of the measurements are discussed on the basis of theoretical titration curves obtained by means of a d igital simulation procedure.
