Removal of antimony (Sb(V)) from Sb mine drainage: Biological sulfate reduction and sulfide oxidation–precipitation

Microbial Antimony Biogeochemistry: Enzymes, Regulation, and Related Metabolic Pathways

“…The generated Sb(III) subsequently bound to the surface of iron (hydr)oxides, which led to the immobilization of Sb. In addition, sulfate-reducing bacteria (SRB) were employed to remove Sb(V) from Sb mine drainage (68). The SRB converted sulfate ions into sulfide that reduced Sb(V) to Sb(III) and resulted in the precipitation of stibnite (Sb 2 S 3 ).…”

Mn assisted electrochemical generation of two-dimensional Fe-Mn layered double hydroxides for efficient Sb(V) removal

“…Antimony (Sb) is causing increasing concern due to its toxicity and biological effects [1,2]. China is the most important Sb producers in the world, where Sb concentration as high as 30 mg L −1 has been reported in the effluents from flotation industries and mine drainage in Hunan province in China, and the development of an effective Sb removal method has become an urgent need [3][4][5].…”

Acetylacetone functionalized magnetic carbon microspheres for the highly-efficient adsorption of heavy metal ions from aqueous solutions

“…2 Thus, it becomes even more necessary to establish a facile and reliable method to deal with environmental pollution of heavy metal ions. Over decades, several technologies have been developed to remove heavy metal ions from wastewaters such as chemical precipitation (including hydroxide precipitation, 3 sulphide precipitation 4 and chelating precipitation 5 ), ion exchange, 6 membrane ltration (including ultraltration, 7 reverse osmosis and nano-ltration 8 and electrodialysis 9 ), coagulation and occulation, 10 otation, 11 electrochemical treatment 12 and adsorption. 13 Adsorption methods draw more attention, because they are simple to pursue without additional consumption, high performing and cost-effective.…”
