Fluoride, a small and monovalent anion with high charge density, is highly mobile in certain metal fluorides and this unique property of fluoride ion makes it attractive for applications like fluoride ion–selective electrodes and batteries based on fluoride ion transport. Most of the fluoride conductivity studies were made on single crystals.

This paper reports that fluorinated PSis with 3,3,3-trifluoropropyl and linear alkyl side chains (F-PSi)s demonstrated monovalent anion size dependent fluorescence quenching, which has potential as a novel type of chemosensor, “monovalent anion indicator”. The extent of the fluorescent quenching was linearly increased by a decrease in the surface charge density of the monovalent anions. In

2017-08-15 · Monovalent anions selectivity measurement.

A monovalent anion selectivity of 1.43 was obtained subjected to the conditions of 1.0 V operating voltage, together with 10 min adsorption time and 30 mL/min feed flow rate. The results in this study are capable of helping develop the PSMCDI (permselective exchange membrane capacitive deionization) technology and expand its application for the removal of fluoride from drinking water.

For example, the Cs + cation is a univalent or monovalent cation, whereas the Ca 2+ cation is a divalent cation, and the Fe 3+ cation is a trivalent cation. Unlike Cs and Ca, Fe can also exist in other charge states, notably 2+ and 4+, and is thus known as a multivalent (polyvalent) ion.
