The absolute value of the impedance of the porous ion exchanger is changed by the ion exchange reaction of various inorganic ions.
In the beginning of the experiment or after the measurement of a certain ion, the ion exchanger was played back by the aforementioned method and reset to the initial condition.
The impedance of the initialized ion exchanger is also shown in the figure.
The impedance |Z| of the ion exchanger increases in accordance with the substitution order of the general ion exchange ([H.
From this result, it was found that the porous ion exchanger with the exchange capacity of [10.
In order to lower the detection limit, it is important to indicate a significant change of the impedance due to adsorbed foreign ions with a low concentration compared with the impedance due to the exchange capacity of the ion exchanger initialized with [H.
The experimental results may suggest that the porous ion exchanger can be expected as one of the promising materials applicable to sensors.
We have investigated ion sensing characteristics of the porous ion exchanger with three-dimensional acceptor for high-performance sensor.
While the conventional ion exchangers have so called "micropores" of [Angstrom] level which are formed at the interspace between the crosslinked polymer matrices, the novel ion exchange monolith features "mesopores" of micrometer order created by the water drops during emulsion polymerization described earlier.
