5;方法精确度高,元素硫检测的相对标准偏差(RSD)＜5%,回收率为93.01%～106.21%.该方法样品用量少,对样品量受限制的工艺等研究特别有利.该方法应用于炼油生产的直馏汽油、催化裂化汽油、催化重整汽油中元素硫的分析测定,效果很好,应用前景广.","authors":[{"authorName":"赵惠菊","id":"c92c90c0-554c-4140-9c0c-2bb4281b5afd","originalAuthorName":"赵惠菊"}],"doi":"10.3321/j.issn:1000-8713.2003.03.005","fpage":"210","id":"399eaf6c-f0d2-431b-822b-629d84f5f544","issue":"3","journal":{"abbrevTitle":"SP","coverImgSrc":"journal/img/cover/SP.jpg","id":"58","issnPpub":"1000-8713","publisherId":"SP","title":"色谱
