Multiparametric curve fitting XVI. Analysis of acid-base titration data on chelating resins.
Methods for treating acid-base titration data on chelating resins are described and applied to the computer-assisted regression program IONEX with the regression procedure MINOPT. In this approach nonideal behavior in the exchanger phase is taken into account by the Högfeldt three-parameter model. Regression analysis is applied to data on Ligandex-I studied by Szabadka and the results compared with those from a least squares program. The two approaches give identical results. The application of regression analysis program is further illustrated on titration data from a commercial chelate exchanger Iontsorb Salycil 100.
