“…Sulphate reduction rates of 17 µmol L -1 day -1 for the unstimulated and 63 µmol L -1 day -1 for the stimulated system were observed. These values are very close to the range reported in similar bench-scale experiments (Burghardt et al 2007). There was no detectable sulphide in the aqueous phase, due to ferrous iron excess at any time.…”

Abstract. Closure of uranium mines often result in formation of acid mine drainage (AMD). Usually AMD contains high concentrations of uranium and other heavy metals, which may influence the ambient environment of the mine. To prevent this, restoration measures are required. A feasible way to ensure pollutant immobilization is the utilization of the mine sites natural-attenuation potential, which may be furthermore enhanced by injection of reactive materials. Stimulation of autochthonous sulphate-reducing bacteria would subsequent lead to a reductive reaction zone within the mine.

“…In addition, INP have also been shown to successfully remediate solutions contaminated with a range of metals, including Pb [10,12,24], Cr [4,10,17,21,24], Cu [4,12,21], As [20,25,26], Ni [12], Zn [12], Cd [12] and Ag [12]. The application of zero-valent INP for the remediation of radionuclides remains less widely researched than for the aforementioned heavy metals and organic contaminants.…”

“…A number of methods have been tried to remove arsenic from the environment [37][38][39]. It is known that ferric chloride and FeO(OH) are useful for the entrapment of arsenic [40][41][42][43].…”
