| Abstract | 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 β-cyclodextrin was prepared for the determination of m-cresol in aqueous medium. Impedance spectroscopic data for this impedancemetric sensor exhibits complex impedance 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 × 10$^{−12}$ to 1.94 × 10$^{−2}$ g/L, 1.79 × 10$^{−12}$ g/L, respectively. In addition to high selectivity for m-cresol, the sensor possesses a good working lifetime. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
