Potentiometric selectivity coefficients of ion-selective electrodes

Part II. Inorganic Anions

(IUPAC Technical Report)

Abstract: Potentiometric selectivity coefficients, KA,Bpot, have been collected for

ionophore-based ion-selective electrodes (ISEs) for inorganic anions reported dur-ing 1988–1998. In addition to the actual numerical values of KA,B

pot together withthe methods and conditions for their determination, response slopes, linear con-centration (activity) ranges, chemical compositions, and ionophore structures forthe ISE membranes are tabulated.

INTRODUCTION

An earlier IUPAC data compilation of potentiometric selectivity coefficients, KA,Bpot, for ion-selective

electrodes (ISEs) was published in 1979 in Pure and Applied Chemistry (PAC) [1]. It covered KA,Bpot data

reported during 1966–1977 and was later followed by another extensive compilation of such data in ahandbook from CRC Press [2]. The latter covered most of the KA,B

pot data reported during the years1966–1988. An updated compilation reported in 1998 was limited to a number of particularly selectiveionophores [3]. Very recently, a data compilation of selectivity coefficients for ionophore-based cation-selective electrodes was published as an IUPAC Technical Report (Part I of this series) in PAC [4].

The present paper compiles the latest KA,Bpot data for liquid-membrane inorganic-anion ISEs based

on neutral and charged ionophores, reported between 1989 and the end of 1998. Moreover, this newcompilation also contains some older data that had not been included in the CRC handbook. The pre-sented KA,B

pot data are listed together with the methods and conditions for their determinations; also tab-ulated are response slopes, linear concentration (activity) ranges, chemical compositions, and ionophorestructures for the corresponding ISE membranes. The present document constitutes the second part ina series. The third part, published separately in this issue of PAC, will cover ISEs for organic ions.

Selectivity coefficients can be measured with different methods that fall into two main groups,namely (1) mixed solution methods, and (2) separate solution methods. The details of the definition ofeach method have been briefly discussed in the first part of this series [4].
