Praseodymium is a rare earth element with various applications. The analysis of the levels of the compounds of this elements is very important and various instrumental techniques have been used for the determination of this element in various samples. Among the various techniques used to this end, electrochemical and optical sensors constitute a set of powerful tools for the determination of traces of Pr3+ ions in various samples and concentration ranges. The present review tends to provide an overview on the various potentiometric and optical sensors developed for this purpose, with a focus on the ionophores used and the composition of the sensing elements.
