title: A facile and high-recovery material for rare-metals based on a water-soluble polyallylamine with side-chain thiourea groups.
abstract: We describe a facile and high-recovery material for rare metals based on a polymer combining amino groups for water solubility and thiourea groups for metal complexation. Good solubility in aqueous metal ion solutions allows for homogeneous and efficient adsorption by the polymer, and a maximum Pd(II) recovery amount (0.508 gPd gpolymer(-1)) greater than those of other polymers reported in the literature.
