| 摘 要： | 综述了清除环境荷尔蒙毒素的研究进展,重点对本课题组近年来采用聚砜和聚醚砜制备的功能高分子微球清除环境毒素的研究进行了综述。微球采用液-液相分离和沉淀的技术制备。多孔性聚砜微球能够有效清除具有大的辛醇-水分配系数的环境荷尔蒙毒素;DNA改性微球对清除具有平面结构的环境荷尔蒙非常有效;采用模板分子印迹的多孔微球对环境毒素不仅具有较高的清除率,且具有一定的分子识别效果,具有更好的发展前景。

| Abstract: | In this paper the recent research progress on the removal of endocrine disruptors are reviewed,especially the removal of endocrine disruptors by functional polymer particles prepared using a phase transition technique from polysulfone and polyethersulfone are reviewed.The endocrine disruptors having high octanol-water distribution coefficients could bind to the polysulfone particles by hydrophobic interaction.DNA-modified particles could more effectively remove environmental hormone with a planar structure.Molecular imprinting particles have specific sites,which allow the specific recognition to endocrine disruptors and high binding amounts to specific endocrine disruptors. |
