| 摘 要： | 采用快速高效的微波消解前处理方法,结合电感耦合等离子体质谱对大米标准物质中砷、铅、镉、硒、铝等元素进行测定,结果表明,选用HNO3∶H2O2=6∶1的酸配比消解效果最好,所得各元素均在质控范围内,回收率均在90%~101%之间,RSD(n=6)均在2.4%~6.1%之间。高通量的微波前处理结合电感耦合等离子体质谱的方法,具有处理量大,操作快速简便等优点,能够满足大米等食品样品的日常监测需求。

| Abstract: | As, Pb, Cd, Se and Al in rice were determined by ICP-MS assisted with a fast and efficient microwave digestion method.The digestion results showed that HNO3∶H2O2=6∶1 was the best acid proportion, and the content acquired for each element was within the scope of the reference standard material.The spiked recoveries were between 90%-101%, and the RSD(n=6) was between 2.4%-6.1%.The proposed method using dometic high-throughput microwave digestion system can meet the needs of daily monitoring for rice samples due to the merits of large handling capacity, rapid and simple operation. |
