Summary: | The authors have studied the possibility of using ion-selective electrodes Kritus (Czecho-Slovakia) for analysis of whole blood and serum without preliminary labor-consuming sample preparation. Chloride ions were found to be detectable in the blood serum by potentiometric titration with Ag nitrate solution making use of a pAg-CE-pF-CE pair in ethanol, acetone, or acetic acid medium. Active concentrations of whole blood and serum bromide- and iodide ions may be measured by direct potentiometry with pBr-CE-pF-CE and pI-CE-pF-CE pairs, respectively, against the background of 1 M potassium (or sodium) nitrate solution providing the constancy of solution ionic strength. |
