Desorption of Metals from Goethite (alpha-FeOOH)

摘要

The transportation, speciation and availability of heavy metals, such as lead, zinc and copper are important environmental concerns primarily because these metals can be toxic to human beings and living organisms. Many industry fields and human being activities, cause metal cycling naturally with direct or indirect ways. Gas emissions from cars, power plants and smelting operations put metals in the air which increase the loadings to soils and aquatic systems. wastes from industries, metal corrosion or leaching from metal-contained products may mobilize a large amount of heavy metals into the environment. It is really important to find the effects of metals to aqueous and soil systems and assess the environmental impacts on environment.
