原子吸收法对土壤铅含量测定效率的提升方案研究

Study on improving the efficiency of atomic absorption spectrometry for determination of lead content in soil

人类的生产活动增加了土壤的铅含量,直接用城市工业废水进行农田灌溉能将大量的铅带入土壤中,燃油和铅冶炼、蓄电池等工业,其产生的三废,也能将铅带入土壤中。现在每年都有200万t未循环利用的铅以各种不均匀的方式进入水、大气和土壤中,造成很多的铅含量异常区。生产农产品用的化肥也会对此产生影响,检测土壤中铅的含量对于整治土壤铅污染,减少铅对动植物的危害具有现实而深远的意义。

the production of human activities to increase the lead content of the soil, the direct use of city industrial wastewater irrigation can be a lot of lead into soil, and fuel battery, lead smelting industry, the waste production, can also lead to soil. There are now 2 million T non recycled lead in a variety of different ways into the water, air and soil, resulting in a lot of lead content anomalies. The use of fertilizers for agricultural products will also have an impact on the detection of lead in the soil for the remediation of lead pollution in the soil, reducing the harm of lead to animals and plants has a practical and far-reaching significance.
