This paper provides an overview of new materials used for anion-sensitive ion-selective electrodes in the past five years. It introduces design variants of anion-sensitive electrodes, their advantages and disadvantages, as well as research methods for assessing their parameters and analytical usefulness. The work is divided into chapters based on the selective ion of the electrode. It presents characteristics of new ionophores used as the electroactive component and other materials used for improving sensor performance such as nanomaterials, composite materials, and hybrid materials. Analytical parameters of the electrodes are collected in tables for easy comparison.
Ion-selective electrodes are a popular analytical tool useful in the analysis of cations and anions in environmental, industrial and clinical samples. This paper presents an overview of new materials used for the preparation of anion-sensitive ion-selective electrodes during the last five years. Design variants of anion-sensitive electrodes, their advantages and disadvantages as well as research methods used to assess their parameters and analytical usefulness are presented. The work is divided into chapters according to the type of ion to which the electrode is selective. Characteristics of new ionophores used as the electroactive component of ion-sensitive membranes and other materials used to achieve improvement of sensor performance (e.g., nanomaterials, composite and hybrid materials) are presented. Analytical parameters of the electrodes presented in the paper are collected in tables, which allows for easy comparison of different variants of electrodes sensitive to the same ion.
