摘要
本法选用硝酸和过氧化氢的混合消解液对黑木耳进行封闭微波消解,用电感耦合等离子体发射光谱仪(ICP-AES)同时测定黑木耳中微量铁、钙、镁、钾、钠、磷的含量。该方法检出限低,方法回收率98.4%～100.6%,相对标准偏差(RSD)0.82%～2.24%,该方法具有良好的准确度和精密度,操作流程短,基体干扰少,并且溶样过程无污染,方法简便、快速,适用于植物样品的批量分析。
The auricularia auricula was decomposed by microwave digestion with HNO3- H202 as mixed digestion liquid, then ICP-AES was applied to simultaneously detect trace Fe, Ca, Mg, K, Na and P in auricularia auricular. The results show that the method has low detection limit, the recovery is 98.4%-100.6%, the variation coefficient RSD is 0.82%-2.24%; The method has great accuracy and precision, short procedure, low matrix interfering, and no contamination during sample dissolving, so it can be used in routine analysis for plant samples.
