N2 - Platinum group metals (PGM) are a group of elements comprised of platinum (Pt), palladium (Pd), ruthenium (Ru), iridium (Ir), osmium (Os), and rhodium (Rh) that are critical for use a wide variety of industries, and their demand will continue to increase with adoption of green energy technologies. This review will describe PGM found in ore and the use of PGM in catalysts, electronics, and fuel cells along with leaching solutions and conditions used for recovery of PGM from both primary and secondary sources. Adsorption has been identified as a promising technology for separating PGM from other base and noble metals from leaching solution due to the physical robustness, high selectivity, and easy tunability of adsorbents. Ligand families, solid supports, capacity, selectivity against base and noble metals, and mechanisms of adsorption found in current literature are described.
