直接浸提分光光度法测定染发粉中的苯胺

Determination of anilinum in dyeing by spectrophotometry with direct marinating

目的：建立染发粉中有毒物质苯胺的分光光度分析方法。方法：用水直接振摇浸提,过滤,分光光度法测定。结果：该方法的回收率在96.0%-101.0%之间,相对标准偏差（RSD）2.8%,苯胺在0-50μg范围内线性良好,相关系数r=0.99992,最低检出限为1.6μg。结论：该方法准确,快速,重现性好,设备简单,可用于染发粉中苯胺的测定。

Objective：To establish the spectrophotometry method for determining anilinum in dyeing.Methods：Anilinum was first extrated by marinating,then was filtered and determined by spectrophotometry.Results：Beer′s law was obeyed in the range of 0～50 μg,relational coefficient being r=0.99992.The relative standard deviation was 2.8%.The recovery was 96.0%～101.0%.Conclusion：This is a simple,rapid and reliable method for determination of anilinum in dyeing with simple device.
