Pu Sorption to Activated Conglomerate Anaerobic Bacteria
The sorption of Pu to the anaerobic bacteria activated under specific conditions of temperature, pH and depleted nutrients after long dormant period was investigated. After 4 h at neutral pH, the distribution coefficient (Kd) between bacteria and aqueous phase at 308 and 278 K had around 103 to 104. After over 5 days, however, the Kd at only 308 K had increased to over 105. Sterilized (dead) and dormant anaerobic bacteria adsorbed Pu to the same extent.
