摘　　要：采用硝酸镁和硝酸消解有机质、固定硫化胶乳中的硫元素,再与氯化钡反应生成硫酸钡沉淀,以此检测硫化胶乳的硫含量。笔者从样品的取样量、硝酸用量、沉淀条件三方面研究测定硫化胶乳中硫含量的具体操作步骤,确保样品检测获得准确的数据。A method for the determination of sulfur in revultex was studied. Revultex was dissociated by using magnesium nitrate and nitric acid , sulfate formed at the same time , which deposited with reacting with barium chloride ,thus the sulfur was determinated quantitatively.The experimental conditions of nitric acid volume and revultex weight and depositing condition were discussed in this paper.
