中国煤中的汞
Mercury in Coal of China
【摘要】 煤中的汞是人们最为关注的环境有害元素之一。由于汞具有强挥发性,燃烧时容易排放到大气中,从而对大气产生污染。我国多数煤中含汞处于0.01~1mg/kg之间,平均0.15mg/kg。煤中黄铁矿是汞的主要载体,其它硫化物、方解石和粘土矿物也可能含汞。燃煤向大气排放汞的问题正日益受到重视。
【Abstract】 Mercury is one of the most important toxic elements in coal.Owing toth e high volatize feature Hg tend to dispose into the air during combustion,and t herefore it result in air pollute.The abundance of Hg in coal of China lies from 0.01 to 1mg/kg with average of 0.15mg/kg。Pyrite is the main container of mercu ry,while the other minerals such as calcite and clay minerals contain some of m ercury.Much attention should be paid to the disposal of mercury into the air.
