| 摘 要： | [目的]建立电感耦合等离子体原子发射光谱法(ICP—AES)测定食品中硼砂含量的方法。[方法]食品样品经湿法消化后,直接采用ICP—AES法测定其中硼元素含量,再换算成硼砂。[结果]硼浓度在0.10～50mg/L范围内线性良好(r=0.9995),相对标准偏差(RSD)均小于2.07,加标回收率为96.0～100.1。[结论]该方法操作简单、分析快速、灵敏、准确,可满足日常大量食品样品中硼砂的检测任务。

| Abstract: | [Objective]To develop a method for determination of borax content in Food sample by inductively coupled plasma-Atomic Emission spectrometry(ICP-AES).[Methods]The samples were digested by wet method,and its borax content was analyzed by the ICP-AES method.[Results]Linearity was obtained in the range of 0.10-50mg/L,with correlation coefficient of 0.999 5.Relative standard deviation(RSD,n = 6)was below 2.07%.Recoveries obtained by the standard addition method were in the range of 96.0%-100.2%.[Conclusion]The p... |
