一种新的方法，硫萃取与适当的有机溶剂和分析的基础上，使用气相色谱法与质谱联用，开发用于识别和定量元素硫的形式在黄铁矿表面。己烷和甲醇提取之间的比较允许两种类型的S-8元素硫的测定：一个馏分单独驻留在黄铁矿表面上，另一个馏分与亲水性表面化合物，如硫酸盐。(C)1999 Elsevier Science B. V.保留所有权利。
A new methodology, based on sulfur extraction with appropriate organic solvents and analyses using gas chromatography coupled with mass spectroscopy, is developed to identify and quantify elemental sulfur forms at pyrite surfaces. The comparison between hexane and methanol extraction allows the determination of two types of S-8 elemental sulfur: a fraction residing alone on the pyrite surface, and another fraction associated with hydrophilic superficial compounds like sulfate.
