WebTetragonal zirconia (t-ZrO 2) nanoparticles (ionophore) are used in newly designed and improved ion selective electrodes for chromium ion detection as an alternative, low-cost, high-precision, and selectivity method.Tetragonal zirconia nanoparticles were synthesized using a modified co-precipitation technique and calcined at 1000 °C for an hour. WebIon-selective electrodes measure activities rather than concentrations. They require a buffer to maintain the ionic strength constant so that concentrations may be used instead of activities. The ion-selective electrode measures the free ion, chemical interferences can occur as a result of, for example, complexation or protonation.
