Praseodymium (Pr) optical sensor based on functionalize of mesoprous SBA-15 paste by N, Ń-bis (salicylidene)-1,3-ethylenediamine Schiff base was prepared. The presented optical sensor membrane is very simple, durable, inexpensive, and capable of reliable response in a wide concentration range. Pr (III) ion can be measured at in the range of 10 to 190 ng mL−1 with a good LOD. This sensor is very useful for the determination of praseodymium ion in waters and synthetic samples.
