A Review on the Potentiometric Lanthanum Sensors

Given the importance of La3+ ions in various areas of medicine and industry and the effects these ions can have on humans and animals, the analysis of the species is an important area in analytical chemistry. In the light of the efficiency of the ion-selective electrodes in the determinations of traces amounts of various analytes, including rare earth ions and lanthanum, all published reports on the development of La3+ ions were reviewed with a focus on the ionophores incorporated therein, their composition and the response and selectivity behavior of the developed sensors, to provide the readers with insight on the various factors influencing the analytical performance of lanthanum selective sensors ions, which can also be applied to research on the development of other rare earth ion sensors.
