Resumen:
The ChG system Agx(Ge0.25Se0.75)100-x with x between 10 and 25 at.% was investigated as membrane material in ion selective electrodes. This system has shown sensibility to the presence of Cu(II) and Fe(III) ions. The introduction of cooper or iron to the ChG composition was made in order to improve the selectivity of the Cu(II)-ISE and Fe(III)-ISE. The analytical properties such as reproducibility, linear range, sensibility, detection limit, response time and working pH range were studied with respect to the ChG composition for the three systems. The cross-selectivity of some interfering ions was investigated.
