چکیده انگلیسی
A highly selective and sensitive PVC membrane, containing phenylurea substituted calix[4]arene was found to be a suitable ionophore for monohydrogen phosphate (HPO42â) ions that exhibited a Nernstian response (with a slope of â29.4 ± 0.3 mV decadeâ1). The working concentration range of the electrode was 6.0 Ã 10â8-1.0 Ã 10â1 mol Lâ1 with a detection limit of 2.0 Ã 10â8 mol Lâ1. The response time of the sensor in the whole concentration range is very short (<8 s), with a considerable lifetime of at least 15 weeks. The sensor possesses the advantages of short response time, low detection limit and a high selectivity towards a large number of inorganic anions. The developed sensor was used as an indicator electrode in potentiometric titration of monohydrogen phosphate ion with barium chloride. The proposed sensor was successfully applied for the direct determination of monohydrogen phosphate in real life samples.
