Abstract: | The preparation of CuI + Ag2S and Cu2HgI4] + Ag2S membranes hydrophobised by PTFE is described. The pressed membranes mounted in a multi-purpose “all-solid-state” electrode body have been examined as electrochemical sensors for Cu2+ and I? ions. For the electrode with (CuI + Ag2S + PTFE)-membrane experimental slopes of 29 mV(pCu)?1 and 62 mV(pI)?1 were obtained, in good agreement with the theoretical values. For practical measurement in solutions where both Cu2+ and I? can be present, the investigated electrode offers certain advantages in comparison with a commercial Cu-ISE. |
