Enhancing Reductive Processes by Autochthonic Sulphate-Reducing Bacteria in Lignite Overburden Dumps

Abstract:

Article Preview

NA-processes can be enhanced for lignite overburden dumps, using dicarboxylic acid as a feasible substrate for autochthonic sulphate reducing bacteria. Sulphate reduction with simultaneous FeS/FeS2-precipitation occurs and immobilises SO4 2-, H+ and heavy metals connected with a decrease of the acidity. The used LC-OCD, HP/LC, isotopic and other chemical analyses substantiate sulphate reduction under technical enhanced conditions too.
