摘要
文章对检测汽油中甲醇含量是否超标方面做出了较系统的研究工作,主要是品红-亚硫酸比色法,本法利用甲醛和品红反应生成蓝紫色物质的颜色深浅,用肉眼就能分辨出甲醇含量的相对大小。文章所建立的方法快速简便,有望运用于加油站现场。
A colorimetric method for fast detecting methanol content in gasoline was studied in detail in the paper.Using formaldehyde and magenta reacts deep violet material,the naked eye can distinguish the relative size of methanol content.The method was expected to use in gas station because of speediness and simpleness.
