Biogenic Iron Compounds for Hazardous Metal Remediation

Abstract:

Biogenic minerals possess particular characteristics, such as high specific surface area and high reactivity, which lead to interesting properties useful in different fields (adsorbents, catalysts, oxidants or reductants). The treatment of effluents charged with heavy metals is attracting growing interest because of environmental and sanitary problems. The anaerobic bioreduction of soluble Fe(III) compounds by a natural consortium from an abandoned mine originates an iron containing precipitate. The aim of this study is the evaluation of the adsorption capacity of the biogenic compounds to treat diluted solutions containing arsenate, chromate and zinc after characterization by Scanning Electron Microscopy and X-ray diffraction analysis.
