荧光分光光度法在苯并（a）芘含量测定上的应用天津港东科技股份有限公司 应用分析部摘要： 荧光分光光度法是对荧光物质进行定性和定量的有效方法。目前国家标准对于测定苯并（a）芘含量的方法主要以荧光分光光度法为主。其中主要的标准有G B11895-1989《水质 苯并（a）芘的测定 乙酰化荧光分光光度法》、G B/T 5009.27-2003《食品中苯并（a）芘的测定》、G B/T 5750.8-2006《生活饮用水标准检验方法 有机物指标 9.2纸层析-荧光分光光度法》等。本文依据国家标准G B/T 5009.27- 2003《食品中苯并（a）芘的测定》，应用港东F- 380型荧光分光光度计对食品中苯并（a）芘含量进行测定。结果证明此方法操作简便，线性良好是测定食品中苯并（a）芘含量的理想方法。 关键词： 荧光分光光度法 苯并（a）芘 水质 食品 生活饮用水 点击查看相关产品：F-380荧光分光光度计· 原理试样先用有机溶剂提取，或经皂化后提取，再将提取液经液-液分配或色谱柱净化，然后在乙酰化滤纸上分离苯并（a）芘在紫外光照射下呈蓝紫色荧光斑点，将分离后有苯并（a）芘的滤纸部分剪下，用溶剂浸出后，用荧光分光光度计测荧光强度与标准比较定量。 &#...</span>
