                                                                                    科研團隊(課題組):環境污染物控制化學
          負責人:蘭葉青 ,025-84396697 ,lanyq102@njau.edu.cn
          研究方向:重金屬污染物控制;有機污染物控制;新穎多功能材料研發;礦山酸性廢水治理 。
          團隊成員:李瑛副教授、國靜講師
          團隊簡介:本研究團隊由1位教授 ,1位副教授和1位講師組成,所有成員均獲得博士學位。本團隊成員近年來一直從事重金屬離子六價鉻的還原去除 ,首次指出了在厭氧的反應體系中,硫化物的氧化產物單質S對硫化物還原Cr(VI)有極顯著的催化加速作用 。發現了不同金屬離子對有機酸還原六價鉻的不同催化作用機理。在有機污染物的降解方面 ,主要研究過渡金屬離子(如Zn(II)和Cu(II)等)活化過硫酸鈉或臭氧等氧化降解有機染料和有機合成中間體等。通過系列研究揭示了過渡金屬離子的催化機理 ,明確了活化中間體和有關影響因素  ,從而爲探索降解環境中的持久高毒的有機污染物的新技術提供科學依據 。在新型功能材料的研究方面 ,目前正在研發介孔磁性材料作爲砷,鉻等高效吸附劑。採用插入、嫁接和合成等方法修飾或改性獲得新型功能材料  ,這種吸附劑不僅具有優越的吸附性能 ,同時因具有高磁性,能顯著提高吸附劑與廢水間的分離效果 。
