Used primarily in solvent extraction processes, this chemical acts as a selective extractant for separating and purifying metal ions, particularly in nuclear fuel reprocessing. It effectively extracts actinides and lanthanides from acidic solutions, making it valuable in the nuclear industry for waste management and resource recovery. Additionally, it is employed in hydrometallurgical processes to recover rare earth elements from ores and industrial waste streams. Its stability and selectivity under harsh chemical conditions make it a reliable choice for complex separation tasks.
