Abstract: A method for rapid detection of sulfur in a gypsum sample by causing emission of sulfur from the sample as vapors, reacting the vapors with silver nitrate and detecting sulfur by monitoring for color change. A kit for rapid detection of sulfur in a gypsum sample is also provided. Further methods include those in which the amount of sulfur in a gypsum sample is quantified in colorimetric analysis with silver nitrate and gypsum standards with known concentrations of sulfur.

Abstract translation: 一种用于通过将来自样品的硫作为蒸气发生硫的方式快速检测石膏样品中的硫的方法，使蒸气与硝酸银反应并通过监测颜色变化来检测硫。 还提供了用于在石膏样品中快速检测硫的试剂盒。 进一步的方法包括其中在比色分析中石膏样品中硫的量被量化的硝酸银和具有已知浓度的硫的石膏标准物。
