Due to their signiﬁcantly harmful impact on the environment and human
health, the qualitative and quantitative determination of cresols receives great attention.
In this study, a highly sensitive and selective polymeric membrane incorporating b-
cyclodextrin was prepared for the determination of m-cresol in aqueous medium.
Impedance spectroscopic data for this impedancemetric sensor exhibits complex impe-
dance over a range of frequencies (1 Hz–100 kHz) and is well-ﬁtted with a proposed
equivalent electrical circuit model. The effect of m-cresol on the high-frequency arc
resistance is described by a linear law at all m-cresol concentrations, indicating the
possibility of utilizing the impedance spectra as the main sensing signal. The linear range
and the detection limit of the calibration curve are 1.79 9 10
to 1.94 9 10
1.79 9 10
g/L, respectively. In addition to high selectivity for m-cresol, the sensor
possesses a good working lifetime.
