201 Removal of metal ion, such as cesium, cobalt, or strontium, from the aqueous solution using microorganism

Abstract

Removal of cesium, cobalt, or strontium ion from the aqueous solution containing each metal ion only using microorganism was examined. Arthrobacter nicotianae which had a high ability to remove cationic metal ion was used for the removal of each metal. The removal of cesium. cobalt, or strontium using A. nicotianae cells was affected by the solution pH, concentration of metal ion, and cell amount. The effects of above mentioned factors on the removal of each metal and time course of strontium from the solution containing each metal only using A.nicotianae cells were reported in this paper.
