“…The Clconcentration was measured using an ion selective electrode (PerfectIon Cl -, Metter Toledo) which responds to the ionic activity of the chloride ions, i.e., it measures the number of effective ions in solution [27]. The directly measured electrode potential, E (V), is related to the activity of the ionic species by the Nernst equation (Eq.…”

Ionic conductivity and capacitance measurements are widely used methods for evaluating the desalination efficiency in capacity deionization processes. In this study, these methods are revised and several problems associated to them identified and evaluated. Furthermore, a new method based on the determination of the chloride ion concentration by means of a chloride selective electrode is proposed as a more reliable alternative for evaluating the desalination performance in these systems. This method has been shown not only to be precise in a wide range of salt concentrations but also to be independent of pH, one of the main limitations of the determinations based on ionic conductivity measurements.

“…[1] Various analytical methods have been developed to determine sulfamethoxazole in formulations and biological samples, such as spectrophotometric [2,3] , chromatographic [4,5] , and HPLC (High Performance Liquid Chromatography) [6,7, 8] methods. The applications of ion selective electrodes continue to be of interest in pharmaceutical analysis [9] and ions [10,11] because these sensors offer the advantages of simple design and operation, reasonable selectivity, fast response, low cost and applicability to turbid and colored solutions [12,13] . In this work the sensor is based on Sulfamethoxazole -tengestophosphoric acid as ion pair in polyvinyl chloride plasticized with different plasticizers were used for the determination of Sulfamethoxazole in pharmaceutical samples, The properties of prepared electrodes, pH effect and selectivity, were studied.…”

Sulfamethoxazole ion selective electrodes were constructed based on sulfamethoxazoletengestophosphoric acid as ion pair complex in a polyvinylchloride matrix and plasticized by four plasticizers, Di-octyl phthalate (DOPH); Tri-butyl phosphate (TBP); Acetophenone (AP) and Nitrobenzene (NB). Sulfamethoxazole electrodes (E1, E2, E3 and E4) gave slopes (52.008, 58.381, 56.909 and 50.309 mV/decade) and linear ranges from (1×10 -5 -1×10 -2 ,1×10 -7 -1×10 -2 ,1×10 -5 -1×10 -2 and 1×10 -5 -1×10 -2 M) respectively. The best electrode (E2) was based on TBP plasticizer which gave a slope 58.381mV/decade, correlation coefficient 0.9997, detection limit of 9×10 -8 M, lifetime 27 day. pH and life time of the electrodes were also studied and the proposed electrode displayed a good stability and reproducibility and were used to determine the Sulfamethoxazole in pharmaceutical samples. The interferences measurements in the presence of (Na + , K + , Cu +2 , Mn +2 , Fe +3 , Al +3 , trimethoprim, starch, sucrose and gelatin) were studied using the separated method and mixed method for selectivity coefficient determination.
