| 摘 要： | 通过微波消解、电感耦合等离子发射光谱法(ICP-OES)分析了江西区域各煤矿煤中Cd、Cr、Cu、Mn、Ni、Pb和Zn等7种金属元素的含量,该7种金属元素在0～5ppm的浓度区间具有良好的线性关系,其相关系数r≥0.9997;回收率为92.55%～114.27%,实验数据真实可靠,结果表明:江西地域煤炭中重金属含量分布较广,各地域煤炭中各金属元素的分布与当地环境有关。

| Abstract: | A new method for determination of metals including Cd,Cr,Cu,Mn,Ni,Pb and Zn in coal powder by microwave digestion and inductively coupled plasma atomic emission spectrometry(ICP-OES) was established.Results demonstrated that the linearity concentration range of these 7 elements were from 0 to 5ppm,with relativity of linear regression equation over 0.9997 and recovery in the range of 92.55%～114.27%.The test showed that the proposed method was simple,rapid with great reliability.Heavy metal elements of coal powder in Jiangxi Province were wide distributed,which were relative to local environment. |
