Acoustic wave sensor for barium based on poly[Ni(salen)(crown)] recognition chemistry.
Interfacial recognition of barium by a crown ether receptor is quantified using an acoustic wave sensor, and the isotherm characteristics rationalized in terms of solution complexation chemistry and polymer materials properties.
