| 摘 要： | 采用微波消解技术处理食用菌样品,用电感耦合等离子体原子发射光谱法(ICP-AES)同时测定锌、铁、锰、铜等微量元素的含量。实验结果表明:优化的消解剂用量为每0.25g食用菌子实体4.5mL HNO3+4.5mL H2O2;该方法适合测定食用菌中的锌、铁、锰、铜等微量元素,具简便、快速、稳定、准确等优点。方法的检出限为0.77～1.54μg/L,加标回收率为91.0%～101%,相对标准偏差为0.95%～7.10%。

| Abstract: | Levels of Zn,Fe,Mn and Cu in fruit bodies of six edible fungi were determined using microwave digestion combined with inductively coupled plasma atomic emission spectroscopy(ICP-AES).Optimal digestion of fruit body material was achieved using a solution of 4.5 mL HNO3+4.5 mL H2O2 to treat 0.25 g tissue.Detection limits and average recovery rates for the four elements ranged between 0.77-1.54 μg/L and 91%-101%,respectively,and RSD values varied between 0.95%-7.1%.ICP-AES represents a simple,rapid and accurate method for measuring trace element levels in edible fungi. |
