| Popis: | A new type of copper(II)-selective electrode has been developed, based on copper(I) sulfide ceramic membranes prepared by an annealing process. The response time was very short even at low concentrations and the potentials were steady and reproducible. The Nernst equation was obeyed in the concentration range of 10 -1 –10 -6 M copper(II) and the analytical range was 10 -1 –10 -8 M . Among the common ions, silver, ammonium, iron(III) and iodide interfered. |
