摘　　要：目的 建立微波消解—铬天青S分光光度法测定食品中铝的方法.方法 以HNO3消解样品后,铬天青S分光光度法来测定铝的含量.结果 该方法的线性范围为0～400 μg/L,相关系数r：0.999 4,最低检测浓度为0.45 μg/L.结论 采用微波消0解—铬天青S分光光度法测定食品中铝含量的方法,方法简便高效,灵敏度高,结果准确可靠.Objective To establish a method that suitable for the detection of aluminum in food by Microwave di- gestion - chrome azure S spectrophotometer. Methods After microwave digested with HNO 3 - H 2 O 2, the con- tent of aluminum was determined by Chrome azure S spectrophotometer. Results The linear range of the method was 0- 400 μg/L, and the correlation coefficient was 0. 999 4, the minimum detectable concentration was 0. 45 μg. Conclusion The method is simple, efficient and high sensitive, and the result is accurate and credi- ble.
