Potentiometric sensing of aqueous phosphate by competition assays using ion-exchanger doped-polymeric membrane electrodes as transducers

Potentiometric sensing of aqueous phosphate by competition assays using ion-exchanger doped-polymeric membrane electrodes as transducers

Using Zn 2+ -BPMP or Cu 2+ -BPMP as a receptor and o -mercaptophenol as an indicator, potentiometric sensing of aqueous phosphate by competition assays was achieved. With attractive features of portability, low cost and resistance to interference from turbidity and color, this sensor was successfull...

Zusammenfassung:Using Zn 2+ -BPMP or Cu 2+ -BPMP as a receptor and o -mercaptophenol as an indicator, potentiometric sensing of aqueous phosphate by competition assays was achieved. With attractive features of portability, low cost and resistance to interference from turbidity and color, this sensor was successfully used for phosphate detection in biological and water samples. Using Zn 2+ -BPMP or Cu 2+ -BPMP as a receptor and o -mercaptophenol as an indicator, potentiometric sensing of aqueous phosphate by competition assays was achieved.
