Abstract |
The development of an ISE for phosphate ions that based on the use of different construction methods is presented. Those constructions were used for the development of analytical characteristics that will allow the direct measurement of phosphate ions in real samples like blood serum and drinking water. The constructions were tested for their selectivity toward phosphate ions, the accuracy of the measurements, the lifetime of the electrode and the reproducibility of the measurements. The complex-formation constant of carrier with phosphate ion is very big. That fact does not allow the reversible interaction of the carrier with the phosphate ion. The result of these is that the electrode is not capable of doing more than one measurement. Additionally an ISE for chloride ion was tested for its ability to measure standard samples like artificial blood serum. The electrodes construction was based on tests for carriers that were carried out in our laboratory. The results of those tests for the lifetime, the reproducibility and the accuracy of the measurements allow the electrode to be used in the future for the direct measurement of chloride ions in real samples.
