标准编号:ISO 334:1992
中文名称:固态矿物燃料.硫总含量的测定.埃斯卡(Eschka)法
英文名称:Solid mineral fuels — Determination of total sulfur — Eschka method
发布日期:1992-12
标准范围
规定的参考方法基于在氧化气氛中点燃与Eschka混合物紧密接触的试验部分(硬煤、褐煤、褐煤或焦炭),去除可燃物并将硫转化为硫酸盐,用盐酸溶液萃取硫酸盐,用氯化钡沉淀进行重量测定。
The reference method specified is based on igniting a test portion (of hard coal, brown coal, lignite, or coke) in intimate contact with Eschka mixture in an oxidizing atmosphere, removal of combustible matter and conversion of the sulfur to sulfate, extraction of sulfate with hydrochloric acid solution and gravimetric determination by precipitation with barium chloride.
