Samarium (Sm) is a rare earth element discovered by French chemist Lecoq de Boisbaudran in 1879. This element is known for its magnetic and optical properties, making it valuable in a variety of high-tech applications. Samarium is often used in the production of optical glass, where it helps to improve the performance of lenses and other optical devices due to its ability to absorb certain wavelengths of light. Additionally, samarium ions play a significant role in ion exchange processes, particularly in the purification of water and other chemical separations.
