摘要
目的:建立电感耦合等离子体发射光谱法测定玻璃白酒瓶中砷和锑迁移量的分析方法.方法:白酒瓶样品使用食品模拟物在 22℃条件下浸泡 24 h,过 0.45 μm微孔滤膜后使用电感耦合等离子体发射光谱仪测定.结果:砷和锑元素在一定的线性范围内线性关系良好,检出限分别为0.05 mg·L-1、0.1 mg·L-1,加标回收率为 91.9%～105.7%,相对标准偏差为 1.36%～4.52%.结论:该方法前处理操作步骤简便、结果精准且检测效率高,适用于玻璃白酒瓶中砷和锑迁移量的高通量检测.
Abstract
Objective:An analytical method for the determination of arsenic and antimony migration in glass Baijiu bottles by inductively coupled plasma emission spectrometry was established.Method:The samples of Baijiu bottles were soaked in food simulant at 22℃ for 24 h,and then measured by using 0.45 μm microporous filter membrane with inductively coupled plasma emission spectrometer.Result:Arsenic and antimony had good linear relationship in their respective linear ranges,and the detection limits were 0.05 mg·L-1 and 0.1 mg·L-1,respectively.The recoveries were 91.9%to 105.7%,and the relative standard deviation was 1.36%to 4.52%.Conclusion:The method is simple,accurate and efficient,and is suitable for the high-throughput detection of arsenic and antimony migration in glass Baijiu bottles.
