中文摘要: 采用国家标准 GB/T23374-2009《食品中铝的测定电感耦合等离子体质谱法》测定 3 种米粉样品中的铝含量,根据 结果分析该方法在实际应用中的改进策略,从干扰消除、样品消解、标准溶液配制和仪器测定条件等方面提出优化改进措 施,并对其有效性进行了测试验证。试验结果表明,改进方法的精密度、重复性和准确度均有较为明显的提高。
Abstract:The content of aluminum in 3 kinds of rice flour samples was determined by the national standard GB/T 23374-2009. According to the results, the improvement strategy of the method was analyzed. The opti- mization and improvement measures were put forward from the aspects of interference elimination, sample di- gestion, standard solution preparation and instrument measurement. And carried out test and verification on its validity, the experimental results show that the precision, repeatability and accuracy of the improved method were obviously improved.
