Project

Analytical Chemistry Division (V)

COMMISSION ON ELECTROANALYTICAL CHEMISTRY (V.5)

Number: 550/58/95

Title: Compilation of K(A,B)pot data

Coordinator(s): Y. Umezawa

Completion Date: 2002 - project completed

Remark: This work was financially supported by Monbusho (Ministry of Education, Science and Culture, Japan) for publication of scientific research results.

Objective:
This is a continuation of a data collection project beginning: PAC 51, 1913-1980 (1979); and PAC 67, 507-518 (1995), on selectivity data for ion-selective electrodes.

Description:
Potentiometric selectivity coefficients have been collected for ionophore-based ion-selective electrodes (ISEs) for inorganic cations reported from 1988 till 1997. In addition to numerical values of K(A,B)pot together with the methods and conditions for their determination, response slopes, linear concentration ranges, chemical compositions and ionophores structures for the ISE membranes are tabulated.

Progress:
1200 references have been collected. A simplified format has been devised for presentation of the data. The entire document entitled 'Potentiometric selectivity coefficients of ion-selective electrodes' will appear in 3 parts:
