Název v původním jazyce

The availability of Cd in aerobically and anaerobically incubated sewage sludge amended by bentonite

Popis výsledku v původním jazyce

Main objective of the investigation was focused on determination of Cd availability in sewage sludge incubated under aerobic and anaerobic environment and amended by bentonite. Stabilised sludges from five different locations with different properties were incubated for eight months with presence of air and without air under controlled conditions (20oC, 80 % humidity). Each sludge was incubated as control treatment and with addition of two rates of bentonite in three replications. The available contentof Cd was extracted by 1 mol.l-1 NH4NO3 every second month and sequential extraction was made twice during incubation. Results showed great differences of Cd availability among tested sludges. Aerobically incubated sludges increased mean amount of mobile Cd in control as well as in bentonite treatments during incubation. Sludge incubated under anaerobic conditions released majority of Cd at the end of incubation.
