“…Due to its specific structure with strong electrostatic interaction and steric resistance, NNPA can form chelating rings with Cu, Ni, Co, and Mn, thereby having strong affinity for Cu, Ni, Co, and Mn. Therefore, NNPA and organophosphorus extractant can be used to develop a novel SSX system, which takes advantage of the SSX system of DNNSA and commercial pyridine derivative extractant while overcoming its disadvantages, resulting in a stable and 21,22 efficient extraction system with high extraction capacity and selectivity towards transition metals.…”
