| 摘要 |
本文研究了使用原子吸收光谱法测定土壤中重金属铅含量时可能遇到的干扰因素，并提出了相应的消除方法。在实验中，发现一些常见的干扰因素，如样品基质的影响、其他金属离子的干扰以及样品预处理过程中的误差等，均可能导致铅测定结果的偏差。为了消除这些干扰，本文通过优化实验条件、选择适当的消除干扰剂以及改进样品处理方法，取得了较为理想的结果。通过合理控制这些干扰因素，能够提高铅测定的准确性和可靠性。本研究为土壤重金属铅的精确测定提供了有效的技术支持。

| Abstract |
This paper investigates the potential interference factors encountered in the determination of heavy metal lead content in soil using atomic absorption spectrometry and proposes corresponding elimination methods. In the experiment, it was found that several common interference factors, such as the influence of sample matrix, interference from other metal ions, and errors in the sample pretreatment process, may all lead to deviations in the determination results of lead. To eliminate these interferences, this paper achieved relatively ideal results by optimizing experimental conditions, selecting appropriate interference eliminators, and improving sample processing methods. By reasonably controlling these interference factors, the accuracy and reliability of lead determination can be improved. This study provides effective technical support for the accurate determination of heavy metal lead in soil.
