摘要: |
分析了采自中国广西清风藤科植物小花清风藤中13种金属元素的含量。小花清风藤茎叶样品经微波消解处理,采用电感耦合等离子体质谱(inductively coupled plasma massspectrometry,ICP-MS)技术检测。钛、钒、铬、锰、铁、铜、锌、砷、硒、铅10种元素采用普通模式检测;为消除多原子离子的干扰,铝、钴和镍3种元素采用了碰撞/反应池技术(collision/reaction cell technology)检测。结果表明试验条件下,硒元素未检出,各金属元素的方法检出限(3s)在0.083~1.564 μg/L之间,方法精密度(n=8)在0.028%~1.510%之间,加标回收率在90%~110%之间。研究结果为了解小花清风藤中金属元素的种类与含量,进一步开发利用小花清风藤提供了参考。 |

Abstract: |
The metallic elements of Sabia parviflora Wall. ex Roxb were analyzed. The sample was treated by microwave assisted digestion, and the contents of 10 metallic elements in the sample solution were determined by ICP-MS. The polyatomic ion effects on the determination of Al, Co and Ni were eliminated by collision cell technique. Values of detection limit (3 s) of the method found were in the range of 0.083~1.564 μg/L, RSDs (n=8) in the range of 0.028 %~1.510 %, and values of recovery in the range of 90.0%~110.0%. The results provide a reference for further development and utilization of Sabia parviflora Wall. ex Roxb.. |
