生活饮用水中重金属铅的检测方法研究

Advances in Determination of Lead in Drinking Water

随着重金属污染在环境污染中日趋严重,重金属的检测技术发展也日新月异。本文主要介绍了用石墨炉原子吸收光谱法测定生活饮用水中重金属铅(Pb)含量的三种不同检测方法,通过实验条件不断对比,优化,使得测定生活饮用水中重金属铅(Pb)含量的检测技术不断完善,能够在以后工作中更加快速、准确的检测出饮用水中重金属的含量。通过三种方法的比较,方法二测的铅标准样品浓度与实际浓度最接近,RSD<10%,由此我们采用方法二来完成生活饮用水中铅的检测工作。

The heavy metal pollution is becoming more and more serious in environmental pollution, the development of detection technology of heavy metals also changes rapidly.The domestic and drinking water was determined by graphite furnace atomic absorption spectrometry in heavy metal lead （ Pb） content of three different test methods, through constant contrast experimental conditions.Through the optimization and the determination of heavy metal lead （ Pb ） in drinking water, content detection technology was constantly improved and able to work in the future in the more rapid and accurate detection of heavy metal content in drinking water.Through the comparison of three methods, the test result of lead concentrations of standard sample, determined by the method 2, was closest to actual concentration, RSD was below 10%.As the result, the method 2 was using to accomplish the detection of lead in water.
