General description
2-Nitrophenyl octyl ether (NPOE) is a solvent used generally for ion transfer in liquid/liquid interface. It shows low solubility in water, low vapour pressure and is less toxic as compared to other organic solvents. It is a good solvent to ionic solutes as it has high molar volume and medium permittivity.
Visit our Sensor Applications portal to learn more.
Application
NPOE was used as plasticizer in preparing PVC-membrane anionic-surfactants-selective electrodes.
Features and Benefits
May be used as a plasticizer for cellulose triacetate membranes providing impermeability to metal cations, but allowing anion exchange.
