“…Table 1 Besides the critical role of the nature of the ion carrier in preparing membrane-selective sensors, some other important features of the PVC membrane, such as the amount of ionophore, the nature of solvent mediator, the plasticizer/PVC ratio, and, especially, the nature of the additives used, are known to significantly influence the sensitivity and selectivity of ion-selective electrodes. [9][10][11][12][13][14][15] As is obvious from Table 1 (No. 5,9 -11), among four different plasticizer used, DBP was a more effective solvent mediator in preparing the imidazole sensor.…”

“…formed. [9][10][11][12][13][14][15] The tube was then pulled out from the mixture and kept at room temperature for 1 h. The tube was then filled with an internal solution (1.0 × 10 -3 imidazole). The electrode was finally conditioned for about 12 h by soaking in a 1.0 × 10 -2 M of imidazole solution.…”

Recebido em 26/2/03; aceito em 24/10/03 Ultra-trace amounts of Cu(II) were separated and preconcentrated by solid phase extraction on octadecyl-bonded silica membrane disks modified with a new Schiff , s base ( Bis-(2-Hydroxyacetophenone) -2,2-dimethyl-1,3-propanediimine) (SBTD) followed by elution and inductively coupled plasma atomic emission spectrometric detection. The method was applied as a separation and detection method for copper(II) in environmental and biological samples. Extraction efficiency and the influence of sample matrix, flow rate, pH, and type and minimum amount of stripping acid were investigated. The concentration factor and detection limit of the proposed method are 500 and 12.5 pg mL -1 , respectively.

A PVC-based membrane electrode for thallium(I) ions based on 1, 21,23,25-tetramethyl-2,20: 3,19-dimetheno-[H, 2] , and a detection limit 5.0 × 10 −6 M. It has a very fast response time of <10 s and can be used for at least ten weeks without a considerable divergence in potentials. This electrode revealed comparatively good selectivity with respect to alkali, alkaline earth, and some transition and heavy metal ions and was effective in a pH range of 2.0-10.0. It was used as an indicator electrode in potentiometric titration of thallium ion with sulfide ion.
