Functional novel ligand based palladium(II) separation and recovery from e-waste using solvent-ligand approach

The global e-waste generation is projected to leap tremendously over the following years due to the fast urbanization and increasing population. Inadequate management and uncontrolled disposal may impact significantly to the health and environment. E-waste could become a significant source of precio...
