摘要
通过采用火焰原子吸收光谱法测定渗滤液中锌含量,对渗滤液中锌含量的不确定度的来源进行分析,找出影响不确定度的因素,使实验结果更具客观性和准确性。实验结果表明:合成标准不确定度为0.012μg/m L,扩展不确定度为0.024μg/m L,渗滤液中锌含量为0.446±0.024μg/m L。
The determination of Zinc in landfill leachate was measured by flame atomic absorption spectrometry, the relevant provisions of the sources of uncertainty for determination of zinc were analyzed and the influent factors of were tbund out, which can make the experimental results more objective and more accurate. The results of calculation and evaluation showed that the combined standard uncertainty was 0.012 μg/mL, the expanded uncertainty was 0.024 μg/mL, and the concentration of zinc in landfill leachate was 0.446±0.024 μg/mL.
