Thermal behaviour of natural and synthetic iron precipitates from mine drainage

Popis výsledku v původním jazyce

TG-DTA, MS detections and XRD were used to characterize thermal behaviour of iron precipitates from acid mine drainage prepared by precipitation with urea and natural iron precipitates sampled from sludge bed (settling pit Sedem A3/4ien and old abandonedadit Hodrua, mining area Banska tiavnica, Slovakia). The high-resolution transmission electron microscopy and scanning electron microscopy (SEM) techniques were used to characterize the surface microstructure and shape of the synthesized and sampled iron precipitates. The SEM micrographs of the iron precipitates (natural and precipitated with urea) show that the samples had formed into agglomerates, probably due to attractive forces of quite large surface area. During heating of the all samples up to 200 A degrees C, physically adsorbed water was removed. On further heating in the range from 250 to 350 A degrees C in natural iron precipitates, the less stable forms (goethite, ferrihydrite, and schwertmannite) transform to more stable f
