Notes:
It was the aim of this work to investigate the sorption characteristics of the Biocermaterial that consists of cells of Bacillus sphaericus that are immobilised on a ceramic carriermaterial, performing column experiments with model waters and real mine drainage waters from aU remediation site in East Germany. In column experiments a nearly quantitative sorption of Cu2+was performed from solutions of different Cu2+ concentrations and at different flow rates. Thedesorption of the Cu2+ in the columns was nearly quantitative in a very short time. The columnscould be regenerated 16 times without a substantial loss of the sorption capacity of the material. Inexperiments with U using real drainage waters, a specific U sorption capacity of 2.34 mg/g wasdetermined. By variation of the experimental parameters, the long-term stability and sorptionproperties of the Biocer columns can be substantially improved
