Bacterial Biosorption Of Heavy Metals From Liquid Wastestreams, Emilia Rus
Bacterial Biosorption Of Heavy Metals From Liquid Wastestreams, Emilia Rus
Theses
In this study, immobilized activated sludge from a municipal wastewater aerobic treatment plant has been evaluated as a potential biosorbent for the removal of heavy metals from liquid waste streams. The method of immobilization consists of entrapment of the microorganisms in calcium alginate beads.
The affinity of immobilized activated sludge to cadmium, lead, chromium and copper has been evaluated under well defined laboratory conditions.
Initially, the time course of metallic ions uptake and the effect of pH and temperature on biosorption were studied for each metal. Then the biosorption pattern and the effect of biosorbent concentration on binding capacity were …
