研究电感耦合等离子体原子发射光谱法(ICP-AES)测定复合食品包装材料中硼含量的最佳仪器条件。对样品的预处理条件和仪器参数分别进行调试,得出最佳条件和仪器参数。结果表明,在所选择的预处理条件和仪器参数条件下,方法的线性良好,在线性范围0~0.500 mg/L内,相关系数达0.999 8,测试样品的准确度和精密度也符合要求。该方法适合批量复合食品包装材料中硼含量的测定。
Optimal instrumental conditions for the determination of boron in composite food packaging materials by inductively coupled plasma atomic emission spectrometry (ICP-AES). The sample pretreatment conditions and instrument parameters were debugged, the best conditions and instrument parameters. The results showed that the linearity of the method was good under the selected pretreatment conditions and instrument parameters. The correlation coefficient was 0.999 8 within the linear range of 0 ~ 0.500 mg / L. The accuracy and precision of the test samples also met the requirements. The method is suitable for the determination of boron content in bulk composite food packaging materials.
