【摘要】：提出了薄层色谱法鉴别黑色签字笔油墨种类的方法,以乙醇(1+1)溶液为提取剂,正丁酮、无水乙醇、水、冰乙酸以体积比14∶10∶6∶1的混合溶液为展开剂,并根据展开斑点的个数、颜色及比移值结果将37种不同产地、不同品牌的黑色签字笔的油墨分为13大类。
[Abstract]:A method for identifying ink types of black signature pen by thin layer chromatography was proposed. Ethanol (11) solution was used as extractant, n-butanone, anhydrous ethanol, water and icoacetic acid as developing agent, and 37 kinds of black signature pen inks from 37 different producing areas and different brands were divided into 13 categories according to the number, color and specific shift value of black signature pen with volume ratio of 14 鈮，
