Title: EFFECT OF THE HEAVY METALS PRECIPITATION ON THE ORGANIC MIXTURES SORPTION AND BUFFERING PROPERTIES DURING BIOREMEDIATION OF ACID MINE DRAINAGE BY MEANS OF MICROBIAL SULFATE REDUCTION

The largest part of dissolved heavy metals and uranium was retained in the anaerobic section for microbial sulfate reduction where the pollutants were precipitated mainly as sulphides and uraninite, respectively. The efficiency of this process was strongly dependent on the rate of biopolymershydrolysis, sorption and bufferingj properties of the used organic mixture. The changes of these properties influenced greatly on the spatial accumulation and the mobility fractions distributions of the retained pollutants that were determined after long permeable barrier's operation.Read More
