施氏矿物吸附Cu~(2+)及氧化亚铁硫杆菌的实验研究
An experimental study of the adsorption of Cu~(2+) and Acidothiobacillus ferrooxidans on schwertmannite
摘要
Abstract
Schwertmannite, characterized by small particle size, high specific surface area and strong surface adsorption energy, is a common secondary mineral formed during the supergene oxidation of sulfides. Due to its adsorption capacity, it can affect geochemical behaviors of heavy metals and microorganism. This study has focused on the adsorption of Cu~(2+) and Acidothiobacillus ferrooxidans cells on the chemically synthesized schwertmannite. It is observed that the adsorption of Cu~(2+) and Acidothiobacillus ferrooxidans on schwertmannite is remarkable, and the biosorption process of Cu~(2+) is well consistent with the Langmuir model. The biosorption process of Acidothiobacillus ferrooxidans, however, is consistent with the Freundlich model instead of with the Langmuir model. It is deduced that the formation of schwertmannite in the ore-formaing environment can strongly affect geochemical behaviors of heavy metals and microorganism and may also affect the decomposing rate of metal sulfides.关键词
