- Abstract:
- A series of hypercrosslinked chelating resins containing sulfur was synthesized by the direct poly-merization of thiophene and bischloromethyl monomers or the introduction of thiophene on hypercrosslinkedresin matrix.The physicochemical structure was analyzed and characterized by elemental analysis,determina-tion of specific surface area and pore size.The results showed that the specific surface area of main chain typeresins can be up to 330.87 m’/g，after post-crosslinking，the resins were polymerized more completely ， sulfurcontent and specific surface area were also improved，sulfur content (5.23 mmol/g) in the side chain typeresin was remarkably superior to the main chain type resin.This study will provide some necessary perform-ance parameters for the actual application of these functional resins in wastewater treatment， separation andconcentration of noble metals，and hydrometallurgy.
