摘要:: 通过噻吩与双氯甲基刚性交联剂的聚合与接枝反应制得一类新型含硫超高交联螯合树脂,并通过元素分析、比表面积及孔径测定等方法对其物理化学结构进行分析和表征.结果表明:主链型树脂的比表面积可达330.87 m2/g经过后交联,树脂聚合更完全,硫含量和比表面积均有所提高侧链型树脂的硫含量(5.23 mmol/g)明显高于主链型树脂.这些研究为该吸附树脂在废水处理、贵金属分离与富集以及湿法冶金等领域的实际应用提供了必要的性能参数.

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.
