摘　　要：采用微波制样技术,用电感耦合等离子体发射光谱(ICPAES)法测定水泥中的硫。结果表明,方法的检出限为0.013μg/g,回收率为96.4％～102.2％,相对标准偏差为0.9％～2.11％。该法准确、快速、简便,已用于水泥中硫的测定。It is reported in this paper that the microwave digestion technique is used in the Inductively Coupled Plasma-Atomic Emission Spectromtry (ICP-AES) method determination of sulphur in cement. The detection limit is found to be 0.013μg/g, the recovery was found to be 96.4%-102.2%, and its RSD to be 0.9%-2.1%. This method is accurate, quick-acquired and convenient. The result on cement determination is satisfactory.
