To avoid the application limitations of the conventional mercury adsorbents,this paper proposed a new idea using magnetic beads from fly ash to oxidize and adsorb the elemental mercury in flue gas.Combing with the problem that the chlorine content in Chinese coal is relatively low,the methods to enhance the mercury capture efficiency of the magnetic beads were developed,on the basis of abundant experimental results.It found that the Co_3O_4 and CuCl_2 modified magnetic beads present good mercury removal cap...
of the absorbed mercury as well.汞是一种神经毒物,具有极强的累积性和不可逆性,对人类健康威胁很大。联合国环境规划署2013年发布的调查报告指出,燃煤电厂是最主要的人为汞污染源之一[1]。为了保护环境,实现可持续发展,2011年我国环境保护部颁布了最新的GB 13223—2011《火?
