CID-ICP-AES检测煤中不同形态的硫

Determination of Different Chemical State of Sulfur in Coal by ICP-AES

研究了 CID- ICP- AES检测煤中硫酸盐和硫铁矿形态硫的方法。较现有国标方法快速、简便 ,常见元素不干扰 ,加标回收率在 98.5 %— 10 3.0 %之间 ,10次测定的 RSD在 0 .76%— 1.5

A ICP-AES of determining different chemical state of sulfur in coal was studied.The proposed method is rapid,simple and selective as compared with the standard method.The recoveries of the method are in the range of 98.5%—103.0%,and the relative standard deviations of determination in 10 samples are in the range of 0.76%—1.59%.
