| 摘 要： | 采用原子吸收光谱法对食用坚果中污染元素铅的含量进行了分析。铅在0.00～2.00 μg·mL-1范围内具有线性关系，r=0.999 1，测定铅的RSD≤4.64%，标准加入法测定铅的回收率94.0%～102.0%，方法简单，结果准确。

| Abstract: | The contents of the pollutant element, lead, in edible nuts were determined by flame atomic absorption spectrophotometry. The linear relationship over the range of 0.00-2.00 microg x mL(-1) is good (r = 0.9991). The recovery is in the range of 94.0% - 102.0% and the RSD is below 4.64% (n = 5). The method is simple and the results are accurate. It can be used as a monitor method for lead in edible nuts. The results show that the pollutant element lead exists commonly in edible nuts. The plants were affected by water, soil and atomsphere during growing, and can absorb lead in environment. |
