摘要
随着工业化和人类活动的增加,土壤和矿物中的重金属污染成为公众关注的焦点.重金属过量积累会对土壤生态系统和人类健康构成威胁,通过工业排放、农业投入、采矿等活动进入土壤和水体中,引起生态环境问题.然而,重金属元素也是许多工业和技术应用中不可或缺的材料,在医疗领域有着重要应用.因此,采取准确、可靠的方法,分析测量土壤和矿物中重金属含量至关重要.目前,有多种分析方法可用于土壤与矿样中重金属的测定,但不同方法的准确度、精密度和应用范围存在差异.因此,本文对原子吸收光谱法(AAS)、原子荧光光谱法(AFS)、电感耦合等离子体质谱法(ICP-MS)、X射线荧光法(XRF)进行比较研究,评估其适用性、准确性和成本效益等特性,对于科学研究和环境监测具有重要意义.
Abstract
With the increase of industrialization and human activities,heavy metal pollution in soil and minerals has become a focus of public attention.Excessive accumulation of heavy metals poses a threat to soil ecosystems and human health,entering soil and water bodies through industrial emissions,agricultural inputs,mining and other activities,causing ecological and environmental problems.However,heavy metal elements are also indispensable materials in many industrial and technological applications,and have important applications in the medical field.Therefore,it is crucial to adopt accurate and reliable methods to analyze and measure the heavy metal content in soil and minerals.At present,there are multiple analytical methods available for the determination of heavy metals in soil and mineral samples,but the accuracy,precision,and application range of different methods vary.Therefore,this article compares atomic absorption spectroscopy(AAS),atomic fluorescence spectroscopy(AFS),inductively coupled plasma mass spectrometry(ICP-MS),and X-ray fluorescence spectroscopy(XRF)to evaluate their applicability,accuracy,and cost-effectiveness,which is of great significance for scientific research and environmental monitoring.
