| 摘 要： | 目的 解决茚三酮溶液在显现手印同时对纸张上字迹产生扩散作的问题;方法 分别采用茚三酮丙酮溶液,茚三酮氟利昂溶液,茚三酮石油谜溶液,茚三酮庚烷溶液作比较。结果 钢笔字迹用4种溶液均不易扩散;纸张上其它成份字迹用后两种方法显现手印时可有效保存纸张上文字原貌。

| Abstract: | To solve the problem of diffusion of handwriting ink when fingerprint on paper were developed by ninhydrin method, we compared four reagents: solution of ninhydrin in acetone, solution of ninhydrin in freon, solution of ninhydrin in petroleum benzine and solution of ninhydrin in heptane and found that for fountain pen ink on paper, there is no diffusion after fingerprint was developed with four reagents, but for other inks, only with last two reagents, there is no significant change of handwriting. |
