矿区土壤中重金属测定方法的研究

Study on the Determination Method of Heavy Metals in Mining Area Soil

在全球经济飞速发展的影响下,矿区重金属过度开采对环境的破坏也随之增加。环境监察的目标之一就是检查矿区土壤含重金属量,因此,本文通过使用微波消解法分解收集矿区重金属样本含量,运用原子吸收分光光度计检测多层次样品中的各种金属含量,将实验检测结果与矿区土壤环境质量国家标准(GB15618-1995)作对比,由此得出矿区土壤是否被铅、隔元素侵蚀。

Under the influence of the rapid development of the global economy,the environmental damage caused by the excessive mining of heavy metals in mining areas has also increased.One of the objectives of environmental monitoring is to check the content of heavy metals in the soil of the mining area.Therefore,this paper uses the microwave digestion method to decompose and collect the content of heavy metals in the mining area,uses the atomic absorption spectrophotometer to detect the various metal content in the multi-level samples,and compares the experimental detection results with the national standard for the environmental quality of the mining area soil(GB15618-1995),so as to determine whether the mining area soil is eroded by lead and other elements.
