%X 利用氧弹燃烧分解煤样， 采用ＪＤＳ２００ 型微分测汞仪测定煤中汞的含量。方法检出限为０．１３ ｎｇ／ｍ Ｌ， 相对标准偏差４．８ ％ ， 回收率８６ ％ ～１１５ ％ ， 校准曲线相关系数０．９９９６ 。试验结果表明， 该方法简便、快速、准确， 能够有效地测定煤中痕量汞。 This article introduces the method of oxygen bomb combustion cold atomic absorption for determination of the mercury in coal. The determination limit is below 0 13 ng/ml and recovery is 86%～115%. RSD is less than 3 0% and the correlation coefficient is 0 9996. The experimental result is show that the method is simple, convenient and accurate. It is a very practical method for analysis of the trace mercury in coal
