Ionophore and polymer membrane selective for aluminum (III) ion

摘要

The ionophore and polymer membrane selective for aluminum (III) ion provide an ionophore that is selective for aluminum (III) ion [Al³⁺].;The ionophore may be used as a dopant in a polymer membrane formed from a polymer matrix, e.g., poly (vinyl chloride) (PVC), and that may also include a plasticizer, such as dioctylphthalate (DOP) and o-nitrophenylloctyl ether (o-NPOE). The polymer membrane may be incorporated into an ion selective electrode (ISE) that can be used as a potentiometric sensor for the detection of Al³⁺ ions in wastewater. The ionophore is diethyl (2-azobenzoic acid) malonate, which has the structure:;
