| 摘 要： | 目的采用液相色谱-原子荧光光谱法(liquid chromatography-atomic fluorescence spectrometry,LC-AFS)法测定紫菜中无机砷含量,比较不同浓度提取剂在不同超声提取条件下提取紫菜中无机砷效果,确立紫菜样品无机砷提取方法。方法采用正交试验的方法分析比较不同浓度提取剂在不同超声提取条件下提取紫菜中无机砷效果。结果实验表明,当硝酸浓度为0.15 mol/L,超声提取时间为60 min,超声提取温度为60℃时,提取效果最好。AsⅢ、AsⅤ回收率分别为87.5%~110%和88.5%~106%,精密度分别为9.56%和8.31%。结论该方法检测准确、可靠,具有良好的精密度,适用于紫菜无机砷的提取、检测。
