Deposition Techniques

Solid-contact Ion Selective Electrodes (SC-ISEs) for the detection of lead are prepared on screen printed substrates in order to have low-cost and disposable sensors which may be useful in long-term environmental monitoring. It is shown that the materials used as solid contact layer, the deposition techniques and their thickness affect greatly the performances of the sensors. Poly(3-octylthiophene-2,5-diyl) (POT) and poly-3,4-ethylenedioxithiophene (PEDOT) are employed in this investigation. A trend showing an optimum is found for sensors prepared with POT as the batch reproducibility depends on the amount drop-cast, i.e., thickness. In case of PEDOT which is grown amperometrically the trend is more complex but an optimum for the batch reproducibility is again found depending on the current density. In the latter case, the film thickness and the overoxidation degree of the polymer probably concur in determining a more complex relationship.

Robust and easy-to-handle ion-selective electrodes in all-solid-state configurations based on graphite paste have been developed for applications in environmental samples. The electrode consists of different functional layers (graphite paste, conducting polymer, ion-selective membrane). The ion-selective compounds have been incorporated in polyvinylchloride (PVC) membranes. Polypyrrole (PPy) acts as a solid contact and an intermediate layer between the ion-selective membrane and the graphite paste. As ion-complexing compounds tridodecylmethylammonium nitrate (TDMA-NO3) for nitrate, N,N,N’,N’-tetra[cyclohexyl]diglycolic acid diamide and N,N-dicyclohexyl-N‘,N‘-dioctadecyl-diglycolic diamide for calcium(II) determinations have been used. The electrodes have been tested in drinking and well water samples by direct potentiometric determination and by titrations. The results have been compared to ion chromatography as the reference method. Both ion selective electrodes exhibit linear response from 10-5 mol/L to 10-1 mol/L respectively. The detection limits for the target ions are below 10-6 mol/L based on the respective ion.
