摘　　要：文章应用连续化学浸提法对淮南不同矿区的煤样进行连续浸提,并根据不同形态砷汞的溶解度将煤中砷、汞分为可交换态、硫化物结合态、有机物结合态和残渣态。利用氢化物发生-原子荧光光谱法对总砷、总汞及各个形态的砷汞进行测定,结果表明,砷汞在淮南煤中主要以硫化物结合态存在,其次为有机结合态和残渣态,可交换态微乎其微。In this paper,the continuous chemical extraction method was used to extract coal samplesfrom differentmining areas in Huainan,and based on the solubility of different forms of arsenic and mercury in coal,theyweredividedinto exchangeable state,sulfide binding,organic combination and the residual form.Arsenic and mercury in various forms were determined by hydride generation-Atomic Fluorescence Spectrometry.The results show that arsenic and mercury in Huainan coal mainly exists in the sulfide biding state.
