Comparative study on heavy metal analysis methods in soil and mineral samples
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.
