  • Ionophore and polymer membrane selective for aluminum (III) ion
    Patent number: 9562885
    Abstract: 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.
    Type: Grant
