摘要:
采用电感耦合等离子体发射光谱和化学分析法对黄陇煤田侏罗纪煤中多种微量有害元素进行了分析,探讨了其在煤中的富集特征。运用相关分析和聚类分析法研究了煤中微量有害元素与工业分析参数、全硫,以及微量有害元素间的相关性和共生组合关系。研究发现:F,Mn,Sr,Ba,Se,P,Cl含量较全国水平明显偏高,U,Cr,Cu,V,Zn等元素含量与全国水平相当。Cl,F,Se具有较强的有机亲和力,Cr,Mn,Cu,V,Zn,Sr,P,Ba,U为亲无机元素。Se,Cl,F主要以有机态存在。Cr,V,Cu,Sr,Zn吸附于粘土
Abstract:
The abundance of hazardous trace elements in coal collected at main active mines in Huanglong Jurassic Period coal field were investigated by inductively coupled plasma optical emission spectrometer and chemical method. Correlation and symbiotic relationship between hazardous trace elements, parameters of proximate analysis, and total sulfur was examined by correlation analysis and cluster analysis. Analysis results show that the abundance of F, Mn, Sr, Ba, Se, P and Cl are markedly higher than average values of Chinese coals, and the abundance of U, Cr, Cu,V and Zn gets close to the average values. Cl, F and Se show organic affinity and Cr, Mn, Cu, V, Zn, Sr, P, Ba and U show inorganic affinity. Se, Cl and F mainly occur in bound-organic. Cr, V, Cu, Sr and Zn are mainly associated with clay minerals. Mn, U and Hg may possibly be existed in pyrite or phosphate minerals. Ba is significantly correlated with barite. Inorganic bound elements have some cleaning potential, but organic bound elements have been enriched by washing.
