Reaction of 1,4-bis(chloromethyl)benzene with the in situ-generated NaHSe afforded a facile fabrication method of poly-selenide, a novel organoselenium material which was found to be efficient for heavy metal removing and recycling. The material could grab transition metals from their aqueous solutions and release them in HNO3. After treating with aqueous Na2SO3, the polymer could be refreshed and reused. It could absorb heavier Pb even than its own weight from high concentration solutions, and remove almost all of the Pb in dilute solutions.
