摘要
本研究建立了一种利用微波消解-原子荧光光度法测定鱼类肝脏中砷含量的方法.通过优化微波消解条件和原子荧光参数,实现了对鱼类样品中痕量砷的高效检测.实验结果显示,当鱼类肝脏样品质量为0.25 g时,检测限低于0.02 μg·L-1,回收率为84.2%～116.4%,相对标准偏差小于3.15%.该方法简便、快速且灵敏度高,适用于水生生物样品中砷的检测,为水体环境监测和食品安全评估提供了一种有效工具.
Abstract
This study established a method for determining arsenic content in fish liver using microwave digestion combined with atomic fluorescence spectrophotometry.By optimizing microwave digestion conditions and atomic fluorescence parameters,efficient detection of trace arsenic in fish samples was achieved.Experimental results showed that with a fish liver sample mass of 0.25 g,the detection limit was below 0.02 μg·L-1,with recovery rates ranging from 84.2%to 116.4%,and a relative standard deviation of less than 3.15%.This method is simple,fast,and highly sensitive,making it suitable for arsenic detection in aquatic biological samples and providing an effective tool for water environment monitoring and food safety assessment.
