摘要
The construction, performance characteristics and application of a novel copper (II) membrane sensor based on a new Dimethyl 4, 4'-(o-phenylene)bis(3-thioallophanate) are reported in this paper. The designed sensor exhibited a wide linear response with a slope of 30.3 mV per decade over the concentration range of 9.8 x 10(-6)-1.0 x 10(-1) M. The potentiometric response is independent on the pH of the solution in the range of 3.1-7.6. The electrode shows a response time of 20 s. The proposed electrode can be used for at least two months without any considerable divergence in potentials. It exhibits very good selectivity relative to a wide variety of alkali, alkaline earth, transition and heavy metal ions. The developed sensor was used for the quantitative determination of Cu (II) ions both in synthetic and real samples. The electrode assembly was also used as an indicator electrode in the potentiometric titration of Cu2+ with EDTA. (C) 2012 Elsevier B.V. All rights reserved.
