摘　　要：利用盐酸-硝酸-氢氟酸-高氯酸-硫酸(五酸)混合体系消解样品,采用电感耦合等离子体发射光谱法(ICP-OES)测定灰化煤样中锰、铜、铅、锌、铬5种金属元素含量。实验结果表明,该方法对这5种待测元素的加标回收率范围在98.60%~102.30%之间,相对标准偏差为0.44%~1.78%。该方法的准确度和精密度满足要求。本方法操作简单、灵敏度高,检测速度快结果准确,能满足煤中多种金属元素同时测定的分析需求。The contents of four metal elements in ashed of coal sample, including Mn, Cu, Pb, Zn and Cr, were analyzed by Inductively Coupled Plasma Optical Emission Spectrometer （ICP-OES）. The sample was digested by HCl/ HNO3/HF/HCIO4/H2SO4. The results showed that the linearity of calibration curves was good, and the recovery of these metal elements was 98.60% - 102.30%. The relative standard deviation was 0. 44% - 1.78%. The method was highly sensitive, simple, rapid and the result was accurate, can be applied for analysis of metal elements in coal.
