Keywords b-Cyclodextrin  Impedancemetric sensor  m-cresol  Polymeric membrane  Equivalent circuit Introduction Environmental contamination by hazardous and toxic chemicals is considered to be a major problem all over the world today [1]. Phenolic compounds, which are regarded as a priority contaminant by the United States Environmental Protection Agency (USEPA), are major toxic pollutants that are commonly observed in the effluent of various industrial waste waters [2–7]. Among such compounds, cresols have been found in ground waters below wood preservation plant areas, in gasworks sites, and in leachates from landfills [8]. Meta-cresol (m-cresol) is a methylated derivative of phenol and is produced commercially by chemical synthesis or by distillation from petroleum or coal tar [9]. Industries such as pulp and paper mills, textile mills, coal gasification units, herbicides and fungicides production, etc., are mainly responsible for discharging m-cresol in their aqueous effluents [10]. The analysis of m-cresol-like chemicals in use for a long period of time has evolved from a number of nonspecific colorimetric methods to more selective separation techniques using gas chromatography (GC) or high-performance liquid chromatography (HPLC) [11]. The complexity, high costs, and large size of these instruments are the reasons that led us to develop http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
