摘要
目的 建立电感耦合等离子体质谱法(ICP-MS)分析食品用紫砂制品中23种金属元素迁移量。方法 在特定的迁移条件下,选择食品模拟物为4%的乙酸溶液,利用电感耦合等离子体质谱法测定食品用紫砂制品中23种金属元素的迁移量。结果 各元素的线性良好,相关系数r>0.999,方法检出限为0.000 5~0.045 0 mg/L,相对标准偏差为1.02%~4.88%(n=6),加标回收率为99.3%~101.7%。结论 该方法精密度好,快捷、准确、高通量,适合于食品用紫砂制品中23种金属元素迁移量的检测。
Objective To analyze the migration of 23 metal elements was purple sand products for food,this paper establi⁃shes an inductively coupled plasma mass spectrometry method.Methods The samples were under the specific migration conditions,the migration amount of 23 metal elements in purple sand products for food was determined by inductively cou⁃pled plasma mass spectrometry(ICP-MS)with 4%acetic acid solution as the food simulant.Results The linearity of each element was good,the correlation coefficient R>0.999,and the detection limit of the method was between 0.0005-0.0450 mg/L.The relative standard deviation was 1.02%-4.88%(n=6),and the recovery rate of standard addition is between 99.3%-101.7%.Conclusion The method is accurate,precise,fast,and high-throughput,which is suitable for the de⁃tection of the migration of 23 metal elements in purple sand products for food.
